Answer» Solution :Same torque is applied to both `tau = I_(1) alpha_(1) = I_(2) alpha_(2)`Thus the angular acceleration is less, if moment of inertia is high. When raw EGG rotates the liquid matter moves AWAY from the AXIS and hence moment of inertia increases. So `alpha` decreases i.e., it comes to rest first Boiled egg BEHAVES as a rigid body and its pins more.
