Question

A body is moving in a circular path with acceleration a. If its velocity gets doubled then find

the ratio of acceleration after and before the change of velocity​

Answer 1

Answer:

It will be 0 .If a travels in a circular path displacement is 0 so velocity is also 0. As acceleration is the rate of change of velocity, it will also be 0.

Answer 2

Answer:

4:1

Explanation:

acceleration in a circular path=(velocity) ^2/radius

let initially velocity=v

and after velocity =2v

acc. after/acc.before=(2v) ^2/v^2=4:1
