Question

A small ball of mass … and density … is dropped in a viscous liquid of density …. After some time, the ball falls with a constant velocity. What is the viscous force on the ball ?

Accepted Answer

Option A. When the ball is falling with a constant velocity, it means the net force acting on the ball is zero. This is because it's in a state of dynamic equilibrium - the downward force equals the upward force.
