Work done by the centripetal force on a body moving in circle is zero because
Correct answer: C. the body move right angle to F
- A. the body moves parallel to F
- B. the body move opposite to F
- C. the body move right angle to F
- D. centripetal and centrifugal balance each other
Explanation
Work done is defined as the product of force into the distance moved in the direction of force. If the body moves at a right angle i.e perpendicular then the work done is zero.

About Work
Work is done when a force produces displacement, with its value determined by the component of force along the displacement. The topic covers positive, negative and zero work, work by variable forces from force-displacement graphs, and the connection between net work and change in kinetic energy.
