When a metallic sphere is dropped in a long column of a liquid, the motion of the sphere is opposed by the viscous force of the liquid. If the apparent weight of the sphere equals to the retardation forces on it, the sphere moves down with a velocity called.

A small metal sphere is falling through castor oil. Name the velocity of the sphere when the unbalanced force on it is zero

A sphere of mass m moving with velocity v collides head-on with another sphere of the same mass at rest. If the coefficient of resistitution e = 1//2 , then what is the ratio of final velocity of the second sphere to the intial velocity of the first sphere ?

A sphere of mass 'm' moving with velocity 'v' collides head-on on another sphere of same mass which is at rest. The ratio of final velocity of second sphere to the initial velocity of the first sphere is (e is coefficient of restitution and collision is inelastic)
