What is the moment of inertia os a solid sphere of radius 3 cm and density 3 `g//cm^(3)` about its diameter in C.G.S. system?

A

`148pi`

B

`388 pi`

C

`138 pi`

D

`216 pi`

Text Solution

Verified by Experts

The correct Answer is:
B
`I = (2)/(5)MR^(2)`
`= (2)/(5)xx3xx(4)/(3)pi xx 27xx3xx3xx = 388 pi "gm cm"^(2)`.
