Hi, this is a question based on work done.
00:03
So, we know that work done is nothing but it is force into perpendicular distance into cos theta.
00:10
So, theta is the angle between the force and the displacement.
00:13
So, here we are given with a f value as 10 newton displacement d is given as 10 meters.
00:19
So, theta is given for each case that is 30 degree, 45 degree and so 60 degree, 90 degree, 4 angles are given we have to find the corresponding work done.
00:33
So, now we have for the first case theta is equal to 30 degree.
00:37
We know that w is equal to force is 10, this is 10 and theta is cos 30 degree.
00:44
So, we have 10 into 10 into root 3 by 2.
00:48
So, we have the answer for first work done is w is equal to 50 root 3 joules.
00:55
In the second part we have to calculate theta is equal to 45 degree...
