A raindrop with radius R=0.2mm falls from a cloud at a height h=2000m 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 water 
and Density of air 
Coefficient of viscosity of air 
]
Text Solution
Verified by ExpertsThe correct answer is:
C
At terminal speed
a=0
Fnet=0
=4.94m/s
