Question

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 '8m' is dropped in same liquid then the terminal velocity will be ____________.

Options

• v

• 2v

• 4v

• 8v

Answer 1

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 '8m' is dropped in same liquid then the terminal velocity will be v.

Explanation:

Terminal velocity is independent of body mass but reliant on material density for a given substance.
