A horizontal platform is rotating with uniform angular velocity around the vertical axis passing through its centre. At some instant of time a viscous
\( \mathrm{P} \)
fluid of mass ' \( m \) ' is dropped at the centre and is allowed to spread out and finally fall. The angular velocity during this period
(1) Decreases continuously
(2) Decreases initially and increases again
(3) Remains unaltered
(4) Increases continuously
