Answer:
When the rain drops fall freely under gravity, their motion is opposed by the viscous drag of air. They attain terminal velocity when the viscous force due to air becomes equal to the weight of the drops. Terminal velocity, \[\upsilon \propto {{r}^{2}}\] As radii of rain drops are small, so they do not acquire very high velocity.
