A sphere is rolling down an inclined plane without slipping. The ratio of rotational kinetic energy to total kinetic energy is

A

`2//5`

B

`2//7`

C

`3//5`

D

`3//7`

Text Solution

Verified by Experts

The correct Answer is:
B
`(K_(R))/(K_(T))= (K^(2))/(K^(2) + R^(2)) = ((2)/(5) R^(2))/((2)/(5) R^(2) + R^(2))= (2)/(7)`
