A horizontal platform is rotating with uniform angular velocity ω around the vertical axis passing through its centre. At some instant of time, a viscous liquid of mass m is dropped at the centre and is allowed to spread pout and finally fall. The angular velocity during this period ___________ a) Decreases continuously b) Decreases initially and increases again c) Remains unaltered d) Increases continuously
