Question

when a force of 20 N acts on a body the body is displacement by 5m if the angle between the force and displacement is 60 degree then find the work done by the force








it answer is (50 J)​

Answer 1

F = 20N

S = 5m

thetha = 60°

Work done = F.S cos thetha

work done = 20×5× cos 60°

cos 60° = 1/2

work done = 50 j

Answer 2

Answer:

50J

Explanation:

F = 20N

s = 5m

θ = 60°

W = Fs.sinθ = 20×5×sin60° = 20×5×½ = 50J
