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 :

Answer»

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

SOLUTION :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)`
