Question

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:
(a) 600 J
(b) 500 J
(c) 60 J
(d) 200 J

Answer

(a) 600 J

Reason — Given,

Force = 200 N

Displacement = S = 3 m

As we know,

Work done = force × displacement in the direction of force

= F × S = 200 × 3 = 600 J
