One solid sphere A and another hollow sp...

One solid sphere A and another hollow sphere B are of same mass and same outer radii. Their moment of inertia about their diameters are respectively `I_(A) and I_(B)` such that :

A

`I_(A) = I_(B)`

B

`I_(A)gtI_(B)`

C

`I_(A)ltI_(B)`

D

`(I_(A))/(I_(B))=(d_(A))/(d_(B))`

Text Solution

Verified by Experts

The correct Answer is:
C
Here `I_(S)=(2)/(5)MR^(2)=0.4MR^(2)`
`I_(H)=(2)/(3)MR^(2)=0.66MR^(2)`
`therefore I_(S)ltI_(H)`
or `I_(A)ltI_(B)`
