Question

how much work is done by a force of 10 n in moving a body through a distance of 2 metres in its own direction

Answer 1

F=10N
S=2m
Work done=F×S=10×2=20Nm=20J

Answer 2

When Force is along the direction of displacement

Work = Force × Displacement
= 10 N × 2 m
= 20 Nm
= 20 Joule

∴ 20 Joule of Work is done.
