Question

Let l_A and L_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.

(a) I_A < I_B

(b) If I_A< I_B, the axes are parallel

(c) If the axes are parallel, I_A< I_B.

(d) If the axes are not parallel ,I_A ≥  I_B.

Answer 1

(c) If the axes are parallel l_A < I_B.
