A body is rolling down an inclined plane. If kinetic energy of rotation is 40% of kinetic energy in translatory state, then the body is a
Text Solution
Verified by ExpertsThe correct answer is:
D
: Rotational kinetic energy is,
(
and v = R
) 
Translational kinetic energy is,

As per question, 
or
For solid sphere, 
Hence, the body is solid ball.
