Question

A force of 20 N displays a body through a distance of 1 m at an angle of 60° from its own direction. Calculate the amount of work done.

Answer 1

Given

Force (F) = 20 N

Displacement (s) = 1 m

Angle between force and displacement θ = 60°

★ Work (W) = Fs cos θ

= 20 × 1 × cos 60°

= 20 × 1 × ½

= 10 J

Answer 2

here is your answer maTe

hope it's helpful ....

Given,

force=20N

Distance=1m

Angle=60°

COS60°=1/2

work done=F.S.Costhita

=20×1×(1/2)

=10J
