Question

A rain drop falling on Earth's surface is in a state of equilibrium.

• A. True
• B. False

Answer 1

The correct option is A

True

A rain drop falls on Earth's surface with a constant velocity. The weight of the falling drop is balanced by the sum of the buoyant force and the force of friction ( or viscosity ) of air. Thus, the net force on the drop is zero, so it moves with a constant velocity and hence, is in equilibrium.
