A raindrop with radius R = 0.2 m m falls from a cloud at a height h = 2000 m above the ground.
Assume that the drop is spherical throughout its fall and the force of buoyance may be neglected, then the terminal speed attained by the raindrop is :
[Density of waterf w = 1000 k g m − 3 and Density of air f a = 1.2 k g m − 3 , g = 10 m ∕ s 2
Coefficient of viscosity of air= 1.8 × 10 − 5 N s m − 2 ]
