A horizontal force F = 14 N acts at the centre of mass of a sphere of mass m = 1 kg . If the sphere rolls without sliding, find the frictional force (in N )

A tangential force F acts at the top of a thin spherical shell of mass m and radius R . Find the acceleration of the shell if it rolls without slipping.

A sphere is rolling on a horizontal surface without slipping. The ratio of the rotational K.E. to the total kinetic energy of the sphere is

Two uniform solid spheres having unequal rdii are released from rest from the same height on a rough incline. Ilf the spheres roll without slipping

A plane srface is inclined at an angle theta. A cube slides down the plane and a solid sphere rolls down the plane without slipping. The ratio of the acceleration of the cube to that of the sphere is

Four identical spheres having mass M and radius R are fixed tightly within a massless ring such that the centres of all spheres lie in the plane of ring. The ring is kept on a rough horizontal table as shown. The string is wrapped around the ring can roll without slipping. The other end of the string is passed over a massless frictionless pulley to a block of mass M. A force F is applied horizontally on the ring, at the same level as the centre, so that the system is in equilibrium. The magnitude of F is
