The angular momentum of rotating body is...

The angular momentum of rotating body is increased by `20%`. What will be the increase in its rotational kinetic energy?

Verified by Experts

Kinetic energy `KE=(L^(2))/(2I)rArrE propL^(2)`
`(DeltaE)/E=(120/100)^(2) (or) (DeltaE)/D=0.44`
`(DeltaE)/Exx100=44%`
