A body `B` is capable of remaining stationary inside a liquid at the position shown in Fig. (a). If the whole system is gently placed on smooth inclined plane and is allowed to slide down, then `(0 lt 0 lt 90^@`)

A body floats in completely immersed condition in water as shown in figure. As the whole system is allowed to slide down freely along the inclined surface, the magnityde of buoyant force

A spherical body of radius R is allowed to roll down on an incline with out slipping and it recheas with a speed v_(0) at the bottom. The incline is then made smooth by waxing and the body is allowed top slide without rolling and now the speed attained is (5)/(4)v_(0) The radius of gyration of the body about an axis passing through the centre is

An object is placed on the surface of a smooth inclined plane of inclination . It takes time t to reach the bottom of the inclined plane. If the same object is allowed to slide down rough inclined plane of same inclination , it takes time nt to reach the bottom where n is a number greater than 1. The coefficient of friction  is given by -

In moving a body of mass m once up and down a smooth incline 0 total work done is (S is length of the plane):

A body is sliding down an inclined plane having coefficient of friction 0.5. If the normal reaction is twice that of the resultant downward force along the inclined plane , then find the angle between the inclined plane and the horizontal.

A sphere of outer radius R having some cavity inside is allowed to roll down on an incline. The incline is then made smooth by waxing and the sphere is allowed to slide without rolling and now the speed attained is (5//4)v_0 . What is the radius of gyration of the sphere about an axis passing through its centre ?

A block moves down a smooth inclined plane of inclination theta . Its velocity on reaching the bottom is v. If it slides down a rough inclined plane of some inclination, its velocity on reaching the bottom is v/n, where n is a number greater than 0. The coefficient of friction is given by -
