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 out and finally fall. The angular velocity during this period.

Uniform angular velocity refers to a constant rate of rotation, where an object moves around a circular path with consistent angular displacement over time. Class 11 Physics Systems of Particle & Rotational Motion CBSE EXAM 2024-25
