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

Origin of surface tension of a liquid is due to

Surface tension in a liquid is due to :

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

A ball rises to the surface of a liquid with constant velocity. The density of the liquid is four time 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
