A cord is wound round the circumference of wheel of radius $r$. The axis of the wheel is horizontal and the moment of inertia about it is $I$. A weight $mg$ is attached to the cord at the end. The weight falls from rest. After falling through a distance $h$, the square of angular velocity of wheel will be:
(1) $\frac{2mgh}{I+mr^2}$
(2) $2gh$
(3) $\frac{2mgh}{I+2mr^2}$
(4) $\frac{2gh}{I+mr^2}$
