Relationship between angular momentum L ...

Relationship between angular momentum L and kinetic energy E of a rigid body in pure rotation is

A

`E = L^(2)//2I`

B

`E^(2) = 2I//L`

C

`L = E^(2) //2I`

D

E = 2IL

Text Solution

Verified by Experts

The correct Answer is:
A
`E = (1)/(2) I omega^(2) " "[because L = I omega]`
`therefore" "E = (L^(2))/(2I)`
