Hello students, let us look on this question.
00:02
So in this question we have given that this is the plan for floor on which a 5 kg block is placed like this.
00:09
This is the 5 kg block and a man applying the 80 newton force and just stretching this in this angle at the angle of 30 degree as we can see in the diagram also.
00:23
And we have to find and this block is moved 6 meter by this man, this is the man and this is the, with the constant velocity, with the constant velocity.
00:37
This work is happening with the help of constant velocity.
00:40
So the question is we have to find the work done by this man, okay.
00:44
Now you will be surprised that the work done is basically 0.
00:48
Work done is 0, option number last one, last one is the correct option, 0...
