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

A rod of length 1.4 m and negligible mass has two masses of 0.3 kg and 0.7 kg tied to its two ends. Find the location of the point on this rod, where the rotational energy is minimum, when the rod is rotated about the point.

Energy is the capacity to do work or produce change, existing in various forms such as kinetic, potential, thermal and chemical. Class 11 Physics Systems of Particle & Rotational Motion CBSE EXAM 2024-25
