Question:

$\text{Let } I_A \text{ and } I_B \text{ be moments of inertia of a body about two axes, A and B, respectively. The axis A passes through the centre of mass of the body, but B does not. Which of the following is correct?}$

Options:

1. $I_A < I_B$
2. $\text{If } I_A < I_B, \text{ the axes are parallel.}$
3. $\text{If the axes are parallel, } I_A < I_B$
4. $\text{If the axes are not parallel, } I_A \geq I_B$

Solution:

$\text{If the axes are parallel, } I_A < I_B$
