MHT CET Physics question
A solid ball of volume 'V' is dropped in a viscous liquid. It experiences a viscous force F. If a solid ball of volume '2V' of same material is dropped in the same liquid, then the viscous force acting on it will be [MHT-CET 2019]
Answer: (C)
Solution
At terminal velocity viscous force equals weight minus buoyancy, which is proportional to volume, so doubling
