Question

calculate the work done by a force 100N acting through a vertical height 20m

Answer 1

Given:
Force=100N
Height = h=20m
Work done =?
Potential Energy is possessed by the object.
P.E= Work done =F x S
= mg x h
Where F value is given as 100N ( mg)

Work done =100×20
=2000joules

Answer 2

Hi!

Force= 100N
Height= 20m
Work done= Potential energy

U= mgh
(F=mg)
U= 100×20=200J

Thus work done= 200J

Hope it helps...!!!
