Question

Ramesh pushes a block with a force of 40N.What is the work done by Ramesh as he displaces the block up to 20cm in the direction of force

Answer 1

Explanation:

force = work × displacement

given,

force=40N

displacement=20cm=0.2m

so,

work=force÷displacement

=40÷0.2=200J

Answer 2

Force = 40 N

(S)Displacement = 20 CM

SI unit of S = m

So 20cm / 100 = 0.2m

Work done = FS

= 40 * 0.2

= 8 joules

Hence, Work done = 8 joules
