Let I(A) and I(B) be moments of inertia ...

Let `I_(A)` and `I_(B)` be moments of inertia of a body about two axes `A` and `B` respectively. The axis `A` passes through the centre of mass of the body but `B` does not. Then

A

`I_(A)n gt I_(B)`

B

`I_(A)lt I_(B)`

C

`I_(A)=I_(B)`

D

`I_(A)=I_(B)` only if both the axes A and B are parallel to each other

Text Solution

Verified by Experts

Relation `I=I_(cm)+md^(2)` exists only for parallel axes. So we can understand that option (d) is correct. If the two axes are not parallel then we cannot deduce any relation between them.
