Question

variarion of viscous force f on a small sphere falling through a medium with the radius of the sphere is represented as​

Answer 1

Answer & Explanation:

The force on a small sphere falling through a medium can be calculated using Stokes Law :

where Force (F) = 6πηrv

where;

π = pi or 22/7 or 3.14

η = viscosity of medium

r = radius of sphere

v = velocity of falling sphere

Hence, radius can be represented as r = F / 6πηv
