If KE of the particle of mass m performing UCM in a circle of radius r is E. Find the acceleration of the particle

A

`(2E)/(mr)`

B

`((2E)/(mr))^2`

C

`2Emr`

D

`(4E)/(mr)`

Text Solution

Verified by Experts

The correct Answer is:
A
Kinetic energy ,`1/2mv^2=E^2=1/2mr(v^2)/(r)=E`
`1/2mra=ErArra =(2E)/(mr)`
