Question

A force of 10 N displaces a body by a distance of 2 m at an angle 60° to its own direction. Find the amount of work done.

Answer 1

Answer:

10 J

Explanation:

coz work done is FS Cos theta

so WD = 10 × 2 × cos60

= 10 J

Answer 2

F = 10 N

θ = 60 degree

S = 2 m

Component of force along horizontal direction is = F cosθ = (10)(cos60) = 5 N

So, work done is, W = (5)(2) = 10 J
