Physics
A block of mass 20 kg is pulled up a slope as shown in the figure given below with a constant speed by applying a force of 200 N parallel to the slope from the initial position A to the final position B. Work done in moving the block from A to B is:
- 600 J
- 500 J
- 60 J
- 200 J

Answer
600 J
Reason — Given,
Force = 200 N
Displacement = S = 3 m
As we know,
Work done = force × displacement in the direction of force
Therefore, work done is 600J.
