A solid sphere is moving on a horizontal plane. Ratio of its translational kinetic energy and rotational kinetic energy is

Options

A. `9mu J`
B. `18 mu J`
C. `27 mu J`
D. `36 mu J`

Answer

C

Explanation

`K_(N)= (1)/(2) mv^(2) (1+ (K^(2))/(R^(2)))= (1)/(2) xx (10)/(1000) xx ((6)/(100))^(2) xx (1+ (1)/(2))= 27 mu J`
