149965 A thin circular ring of mass \(m\) and radius \(R\) is rotating about its axis perpendicular to the plane of the ring with a constant angular velocity \(\omega\). Two point particles each of mass \(M\) are attached gently to the opposite ends of a diameter of the ring. The ring now rotates with an angular velocity \(\omega / 2\). Then, the ratio \(\mathrm{m} / \mathrm{M}\) is

149966 A solid sphere is rotating freely about its symmetry axis in free space. The radius of the sphere is increased keeping its mass same. Which of the following physical quantities would remain constant for the sphere?

149968 Angular momentum is

149969 Two particles of masses \(m_{1}\) and \(m_{2}\) have equal kinetic energies. The ratio of their momentum is:

149971 Assertion: Torque on a body can be zero even if there is a net force on it.
Reason: Torque and force on a body are always perpendicular.
