A solid cylinder of mass 2 kg and radius 0.2 m is rotating about its own axis without friction with angular velocity 5 rad/s. A particle of mass 1 kg moving with a velocity of 5 m/s strikes the cylinder and sticks to it as shown in figure.


The angular velocity of the system after the particle sticks to it will be:

If $ A $ is the areal velocity of a planet of mass $ M $, then its angular momentum is:

Joule second is the unit of

An electron has a mass of $ 9.1 \times 10^{-31} \, \text{kg} $. It revolves round the nucleus in a circular orbit of radius $ 0.529 \times 10^{-10} \, \text{m} $ at a speed of $ 2.2 \times 10^6 \, \text{m/s} $. The magnitude of its angular momentum is

A thin circular ring of mass $ M $ and radius $ R $ rotates about an axis through its centre and perpendicular to its plane, with a constant angular velocity $ \omega $. Four small spheres each of mass $ m $ (negligible radius) are kept gently to the opposite ends of two mutually perpendicular diameters of the ring. The new angular velocity of the ring will be
