A solid sphere of radius R is placed on smooth horizontal surface. A horizontal force F is applied at height h from the lowest point. For the maximum acceleration of centre of mass, which is correct?

Acceleration is the rate of change of velocity of an object over time, indicating how quickly it speeds up or slows down. Class 11 Physics Systems of Particle & Rotational Motion CBSE EXAM 2024-25

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
