Let I be the moment of inertia, of a uniform square plate about an axis AB that passes through its center and is parallel to two of its sides. CD is a line in the plane of the plate that passes through the center of the plate and makes an angle θ with AB as shown in the figure. The moment of inertia of the plate about the axis CD is then equal to

A boy stands over the centre of a horizontal platform which is rotating freely with a speed of 2 revolutions/s about a vertical axis through the centre of the platform and straight up through the boy. He holds 2kg masses in each of his hands close to his body. The combined moment of inertia of the system is 1kgm^2 . The boy now stretches his arms so as to hold the masses far from his body. In this situation, the moment of inertia of the system increases to 2kgm^2 . The kinetic energy of the system in the latter case as compared with that in the previous case will
