A particle of mass m is observed from an inertial frame of reference and is found to move in a circle of radius r with a uniform

speed u. The centrifugal force on it is

A. towards the center

B. away from the center

C. along the tangent through the particle

D. zero.

Answer :

Centrifugal force is a pseudo force used in non-inertial frame of reference, when we want to use Newton’s laws. But here the reference frame is inertial, hence there is no centrifugal force.
