Question

Force of 15N acts on a body such that the body moves through.a distance of 50cm in the direction of the force. find the work done by the force

Answer 1

Force is 15N
Displacement is .5Metre
then
w=f X d
w=15X .5
w=7.5Joule

Answer 2

Force=15N

distance=50 cm=.5 m

workdone=Fd

                 =15*0.5

                =7.5 joule
