Solution
When a solid ball of volume V is released in a viscous liquid it experiences a viscous force F. If the solid ball of the same material of volume V/2 is released in the liquid then the viscous force will be F/2.
Explanation:
`"F" prop "r"^3 prop "V"`
As volume becomes doubled, F changes to F/2.
