A smooth ring of mass `m` and radius `R = 1 m` is pulled at `P` with a constant acceleration `a= 4 ms^(-2)` on a horizontal surface such that the plane of the ring lies on the surface. Find the angular acceleration of the ring at the given position. (in `rad//s^(2)`)

A metal ring of mass m and radius R is placed on a smooth horizontal table and is set rotating about its own axis in such a way that each part of the ring moves with a speed v. Find the tension in the ring.

A non - conducting ring of mass m = 4 kg and radius R = 10 cm has charge Q = 2 C uniformly distributed over its circumference. The ring is placed on a rough horizontal surface such that the plane of the ring is parallel to the surface. A vertical magnetic field B=4t^(3)T is switched on at t = 0. At t = 5 s ring starts to rotate about the vertical axis through the centre. The coefficient of friction between the ring and the surface is found to be (k)/(24) . Then the value of k is
