Questions
When a ball is released from rest inside a very long viscous liquid, its downward acceleration is ‘a’ (just after release). Find the acceleration of the ball when the ball has acquired two third of its maximum velocity.
detailed solution
Correct option is A
At release,Wefft = (mg –buoyant force) = ma Viscous force at maximum velocity Weff=Fv 23Weff is the viscoous force when velocity is 23 of maximum velocity ∴Weff−23Weff=FnetSimilar Questions
