Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFExplanation:
The terminal velocity of the spherical raindrop can be defined as,
where, r = radius of the sphere, η = viscosity of the medium, ρ1 = density of sphere & ρ2 = density of medium
From equation (1) we can say that-
Terminal velocity, vt ∝ r2.
Hence, Option 3) is the correct choice.
