Question

Rain drop is falling under gravity on the earth surface. Its speed remain constant near the

earth surface, this constant speed is known as terminal velocity. This velocity depends on

viscosity of air 0

, radius of drop (r0

), difference in density of water and air (d0

) and acceleration

due to gravity (g). Then terminal velocity is [Given that : F = 6rVT

] : ha
