A body is rolling down an inclined plane. Its translational and rotational kinetic energies are equal. The body is not a
(1) solid sphere (2) hollow sphere
(3) solid cylinder
(4) hollow cylinder

A

Solid sphere

B

Hollow sphere

C

Solid cylinder

D

Hollow cylinder

Text Solution

Verified by Experts

The correct Answer is:
D

`K_(T)= K_(R)`
`rArr (1)/(2) mv^(2) = (1)/(2) mv^(2) ((K^(2))/(R^(2)))`
`rArr` K = R hollow cylinder.
