A) \[6\pi \eta {{a}^{2}}v\]
B) \[\frac{6\eta v}{\pi a}\]
C) \[6\pi \eta av\]
D) \[\frac{\pi \eta v}{6{{a}^{3}}}\]
Correct Answer: C
Solution :
Stokes established that if a sphere of radius a moves with velocity v through a fluid of viscosity \[\eta ,\]the viscous force opposing the motion of the sphere is \[F=6\pi \eta av\]You need to login to perform this action.
