A particle performing uniform circular m...

A particle performing uniform circular motion gas angular momentum `L`. If its angular frequency is double and its kinetic energy halved, then the new angular momentum is :

A

2L

B

4L

C

`(L)/(2)`

D

`(L)/(4)`

Text Solution

Verified by Experts

The correct Answer is:
A
Angular momentum, `L = I omega = I (2pi f)`
Frequency `f` is doubled. Hence, angular momentum will become `2L`.
