A massless thin hollow sphere is completely filled with water of mass `m`. If the hollow sphere rolls with a velocity `v`. The kinetic energy of the sphere of water is : (Assume water is non viscous)

A

`1/2 mv^(2)`

B

`1/3 mv^(2)`

C

`7/10 mv^(2)`

D

`5/6 mv^(2)`

Text Solution

Verified by Experts

The correct Answer is:
A
Liquid gets only translatory motion in side any roll mosum. This `kE=1/2mv^(2)`
