Question

A body is moving in a vertical circular motion. Which one of the following forces does it not experience?

(a) Force of gravity

(b) Centripetal force

(c) Normal reaction force

(d) Centrifugal force

I got this question in quiz.

I'd like to ask this question from Uniform Circular Motion topic in section Motion in a Plane of Physics – Class 11

Answer 1

The correct choice is (c) Normal reaction force

The explanation is: A body moving in vertical circular motion experiences these four forces – centripetal force, centrifugal force, force of gravity, and resistance offered by the medium in which it is moving. Apart from these, it does not experience any other force in normal conditions.
