A ball rises to the surface of a liquid with constant velocity. The density of the liquid is four lime the density of the material of the ball. The frictional force of the liquid on the rising ball is greater than the weight of the ball by a factor of

Name the liquid in which iron ball sinks.

A small solid ball is dropped from a height above the free surface of a liquid. It strikes the surface of the liqiud t=0 . The density of the material of the ball is 500m^(3) and that of liquid is 1000 kg//m^(3) . If the ball comomentarily at reast at t=2 sec then initial height of ball form surface of liquid was (neglect viscosity):

A small ball is dropped from a certain height on the surface of a non-viscous liquid of density less than the density of ball. The motion of the ball is

A small ball is dropped from a certain height on the surface of a non-viscous liquid of density less than the density of ball. The motion of the ball is

For a ball falling in a liquid with constant velcoity, ratio of resisitance force due to the liquid to that due to gravity is

A ball weighs 80 g in air 60g in water and 50g in liquid if the density of water is 1gcm^-3 find the density of this liquid.

A metal ball is being weighed in liquid whose temperature is raised continuously. Then the apparent weight of the ball
