Answer 1

☆$\red {HELLO\:DEAR}$☆

When a force F acts on an object to displace it through a distance S in its direction,

then the work done W on the body by the force is given by:

Work done = Force × Displacement

W = F × S

Where,

F = 7 N

S = 8 m

Therefore, work done, W = 7 × 8

= 56 Nm

= 56 J
