Rotational MotionHard
Question
A horizontal platform is rotating with uniform angular velocity around the vertical axis passing through its centre. At some instant of time a viscous fluid of mass ″m″ is dropped at the centre and is allowed to spread out and finally fall. The angular velocity during this period : -
Options
A.Decreases continuously
B.Decreases initially and increases again
C.Remains unaltered
D.Increases continuously
Solution
As viscous fluid spreads a towards continuously then MI increases so ω decreases.
