The moment of inertia of a thin square plate ABCD of uniform thickness about an axis passing through the centre O and perpendicular to the plate is:(i) I1 + I2 (ii) I3 + I4(iii) I1+ I3 (iv) I1 + I2+ I3 + I4where I1 ,I2, I3 and l4 are respectively the moments of inertiaabout axes 1,2,3 and 4 which are in the plane of the plate.
