Force F applied on a body moves it through a distance S along F. The energy spent is :
- F x S
- F/S
- FS2
- F/S2

Answer
F x S
Reason — When a force moves a body through a displacement in the same direction as the force, the energy spent by the force equals the work done.
Work done is defined as the product of the force and the displacement in the direction of the force. Therefore, if a force F moves a body through a distance S along its direction, the work done (and hence the energy spent) is given by,
W = F × S
