Question

Under what condition is the work done by a force equal to zero?

• A. Only A
• B. Only B
• C. Both A and B
• D. Neither A and B

Answer 1

The correct option is C

Both A and B

Displacement is zero when:

1. If a body is acted upon by a force but the net displacement is zero, then the work done will also be zero.
2. The angle between the direction of force and displacement is 90°: Whenever the applied force on the body is perpendicular to the direction of the displacement of the body, then the work done by the force on the body is zero.

Hence, option (C) is the correct option.
