A cylinder full of water is rotating about its own axis with uniform angular velocity `omega`. Then the shape of free surface of water will be

A cylinder of water, is rotating about its own axis with uniform angular velocity ω. The shape of free surface of water will be

A ceiling fan is rotating about its own axis with uniform angular velocity omega . The electric current is switched off then due to constant opposing torque is its angular velocity is reduced to (2 omega)/3 as it completes 30 rotations. The number of rotations further it makes before coming to rest is
