A solid ball is falling through a viscous liquid of viscosity `n`. It has a terminal speed of `15m/s`. Now we take another solid ball of same material but radius twice the first ball falling, through same liquid, what is the new terminal speed (in `m/s` )?

A small spherical ball falling through a viscous medium of negligible density has terminal velocity v. Another ball of the same mass but of radius twice that of the earlier falling through the same viscous medium will have terminal velocity

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).

A steel ball of mass m falls in a viscous liquid with terminal velocity v, then the steel ball of mass 8m will fall in the same liquid with terminal velocity

The terminal velocity V of a spherical ball of lead of radius R falling through a viscous liquid varies with R such that

A spherical ball falls through viscous medium with terminal velocity v . If this ball is replaced by another ball of the same mass but half the radius, then the terminal velocity will be (neglect the effect of buoyancy.)

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

Two spheres of the same material, but of radii R and 3R are allowed to fall vertically downwards through a liquid of density o. The ratio of their terminal velocities is

A spherical metal ball of mass m and radius (r ) is falling through a viscous medium. The value of its terminal velocity is proportional to

A small metal ball of mass m is dropped in a liquid contained in a vessel , attains a terminal velocity v . If a metal ball of same material but of mass 8 m is droped is same liquid then the terminal velocity will be

Two drops of same radius are falling through air with steady speed v. If the two drops coalesce, what would be the terminal speed –
