Question

The centripetal force acting on a body moving in a circle of radius r is F if the body moves in cicle of radius 1/4 of initial value keeping speed constant then percentage change in centripetal force?

Answer 1

Answer:

Centripetal acceleration ac is the acceleration experienced while in uniform circular motion. It always points toward the center of rotation. It is perpendicular to the linear velocity v and has the magnitude ac=v2r;ac=rω2 a c = v 2 r ; a c = r ω 2 .
