Question
A sphere of mass M and radius R is falling viscous fluid. The terminal velocity attained by the falling object will be proportional to :
Options
A.R2
B.R
C.1/R
D.1/R2
Solution
For a falling body in viscous fluid the terminal velocity is related to radius as follows.
VT =
R2(ρ - σ)g ⇒ vT ∝ R2
VT =
R2(ρ - σ)g ⇒ vT ∝ R2Create a free account to view solution
