Question

A force of 20 N being applied on a body ；if the angle between the line of action and the dosplacement is 45, and the amount of displacement is 4 m, then find out the work done.

Answer 1

Explanation:

When force applied is not in the direction of displacement then the

W=Fscos(theta)

Given:

Force applied= 20N

displacement= 4 m

Angle of force= 45°

To find:

Work done

Formula:

W= Fscos(theta)

Solution:

W= 20×4×cos(45°)

= 20×4×(√2/2)

= 20×2(√2)

= 40√2 J
