A sperical object of mass 1kg and radius 1 m is falling vertically downward inside a viscous liquid in a gravity free space. At a certain instant the velocity of the sphere is 2 m/s. if the coefficient of viscosity of the liquid is `(1)/(18pi)N-S//m^(2)` then velocity of ball will become 0.5 m/s after a tie

A spherical object of mass 1 kg and radius 1m is falling vertically downward inside a viscous liquid in a gravity free space. At a certain instant the velocity of the sphere is 2 ms^(-1) . If the coefficient of viscosity of the liquid is (1)/(6pi) SI units, then velocity of ball will become 0.5 ms^(-1) after a time.
