When a spherical body falls through a viscous fluid, it experiences a viscous force, the motion of the body is

The viscous force on a spherical body, when it moves through a viscous liquid, depends on the radius of the body, the coefficient of viscosity of the liquid and the velocity of the body.Find an expression for the viscous force.

When a solid ball of volume V is falling through a viscous liquid, a viscous force F acts of it. If another ball of volume 2 V of the same meterial is falling through the same liquid then the viscous force experienced by it will be (when both fall with terminal velocities).

The backward viscous force acting on a small spherical body falling through a fluid_______with the increase in velocity of the body.

A solid ball of volume V is dropped in a viscous liquid. It experiences a viscous force F. If the solid ball of volume 2V of same material is dropped in the same fluid, then the viscous force acting on it will be

A solide ball of volume V is dropped in a viscous liquid. It experiences a viscous force F. If the solid ball of volume 2V of same material is dropped in the same fluid, then the viscous force acting on it will be

When a sphere falling in a viscous fluid attains a terminal velocity, then

Viscous drag force on a spherical body of radius r moving with speed v in a liquid is F. Viscous drag force on a spherical body of same material having radius 2r moving with speed 2v in same liquid will be?

A small spherical body of radius r is falling under gravity in a viscous medium. Due to friction the meduim gets heated. How does the rate of heating depends on radius of body when it attains terminal velocity?
