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)/(2) mv^(2) = E`
`(1)/(2) mr(v^(2))/(r) = E`
`(1)/(2) mra = E`
`a = (2E)/(mr)`
