If the angular momentum of any rotating ...

If the angular momentum of any rotating body increases by `200%`, then the increase in its kinetic energy

A

`400%`

B

`800%`

C

`200%`

D

`100%`

Text Solution

Verified by Experts

`L_(1)=L, L_(2)=3L`
`(K_(2))/(K_(1))=9, ((K_(2))/(K_(1))-1)xx100=800%`
