Parallelogram law of vectors || 11th physics practical #11thphysics @a2zpractical991

Hello friends and welcome to my channel I'm Sachin Shukla and you are watching A2Z Practical. Today's experiment is Experiment No. 4 Parallelogram Law of Vectors How to conduct this experiment How to set a parallelogram How to get graph paper How to get reading We will see all these things in this experiment. So you do one thing Subscribe to this channel So that you can get more videos Related to this channel The setup you are seeing The black wooden board This is called a parallelogram. Law of force apparatus There are two hangers. There are four weights. 1, 2, 3, 4 And per 50 grams And how much is here 1, 2, 3, 4 And how much is here 1, 2, 3, 4, 5 50 grams And how much weight is here 4 And how much is here 5 And we have added one more weight 1, 2, 3, 4, 5 And we will call it O Now what we are going to do Can you see this thread? What happens to the thread? A shadow is created behind You can see here What you have to do Add a point on the shadow Like If you conduct the experiment You will see The thread In the triangle A shadow is created behind the thread. I can see here If you can't see You can create a shadow. With the help of scale I will add here In the middle A point In the middle I will attach here OK A This side I will create a shadow here. OK A shadow is created here I will create here If you want to draw a fine line I will attach here A point I will attach here So that I can get a good Image I'm plotting a lot of points here If you create 3 dots on the thread You will not face any problem. I have created 3 dots here And 3 dots here You have to set it up like this You have to hang it on the hanger. I have added a point. I have added a point on the shadow. With the help of a pencil I will remove this Let's see Nails I will remove this You can see dots on the paper We have to draw a line. Let's see So friends The shadow we created You can see the points You have to draw a line. 100 What is being given here? It's not 100; it's basically ours. Go and see, it's 98 How much is ours? 98 So, what's the total angle we've got now? 98 degrees Okay? You're absolutely great. It will be written as this, it's 98 degrees What should I do now, friends? A pencil is needed for the rounder. Stay right here, make sure you're comfortable with this. Right? So your The P side, this is your P. This is your queue, so P side But wait, how many grams was ours, fifty? It was four centimeters, then you had Here it is, right? Four centimeter, and Meaning from this point, I mean middle From that point, on the Q side You need to make it 4 cm. And from here, you need to place it on this. Cut back 4 cm from here. Okay How much did you take from the site, Cuba? Four were taken, but the weight was the same. So, you mean I have to bring it back here from the rear, that 40 cm? So you have to put it back here from behind. To be proud Meaning, the more weight you take here, the more centimeters you'll have to carry. And it will remain to be cut. Stay calm, as one should act according to the circumstances. To sustain the life of the living beings, O Lord Samasadu, grant us food. Now you have to connect that line so that the corners match. This line is for Galka. Your life is to live, not to break. Now make it a straight line exactly Connect here and search. They both merge deeply into their own lives. Now here you can see that this Who will treat the disease from K? And they can even drop it themselves. You don't necessarily have to do what you don't want to do. How much was the younger one, the friend below? There were five sons. How many sons were there in it? Five. So, if you're about to major in this, you're seeing it now. It's coming around 5 in one minute. Where exactly is the one written going? Going up to 5 4.8 is I took about 5 kilograms below. So how much is it coming, we're getting 4.8 So, let me tell you how you should write this here, this is the wedge. You took 200 here You also took 200, didn't you? Alright, what's your angle? 98 Okay, and what about your opinion below Was hanging down It was hanging there, right here, this one here Here, on the hang position, look here One two three four five therefore The distance that I have here How much was Major Kaya coming my way? This is perfect. However many grams you take here, it's 50 grams. As many people are waiting here, so many Here you are looking: one, two, three, four, five He was coming, around how much? It's the second place near Phai Bae. You've been to one place Here are the points, so Here, smoke is rising. You have lied. There's something to talk about here. How much I had here, you all showed it When he took the child, this How much did I get? How many centimeters did I get? 4.8 We will see it from calculation now After this, you know that W1 is 200 for you. Q2 What is your weight, Q? How much is it? 200 Your angle is 98 degrees. Now, how much you got from Diagonal—this would be your Diagonal. How much did you get from the diagonal? 4.5 So this will be 4.5 here. It was 50 weight. So you need to multiply this. Multiply 4.8 by 50 So how much will it be today, 240? You don't need to do anything now. When your beta value The value that has come to me It has come too much. compared to the 90s Because my score is 98 So 98 minus 90 gives the value of theta What is this here with me? How much will this be? Do you know the value of the square of 200? plus the value of Q squared equals 200 minus 2 into PQ What is your PQ? 200 What is 200? Into sign theta What is the value of sine here? Please state the value here. 98 Correct If you square 200, you will get 40,000 plus 40,000 Okay You will multiply this completely by 2. Then you will get it. You will get it. Let me tell you how to solve this. So you have to do Add 90 plus 8. The sine of 90 degrees is 1. So it will be here. cos 8 degree Do you know what cos 8 is? Its value is 0.1455 So you can place it directly here. 0.1455 You will solve this completely. Whatever value comes in the square root You will get it if you fully solve it. 250 How much will you get? 250 mean value of unknown weight r The weight of your diagonal How much was it here? 250 Is this it? So, what was your diagonal's weight? This is the 240 one So what will you write here, 240 And the calculation you have right now How much is 250, this both values The difference is just a little bit, almost the same. So there might be an error, so approximately If you implement this practically, you will obtain both of these values the unknown weight of the same coming If the body is provided, how much will we get? 250 So, friends, you must have seen the experiment parallelogram that is Calculation is involved here, and it's easy. gets solved, so thank you for watching This video and please subscribe to A to Z Practical Thank you, friends, I have another channel as well.
