Momentum and CollisionHard
Question
A hole is made at the bottom of a large vessel open at the top. If water is filled to a height h, it drains out completely in time t. Then time taken by the water column of height 2h to drain completely is
Options
A.√2 t
B.2 t
C.2√2 t
D.4 t
= (av) = a
⇒ 
⇒ t = 
⇒ t ∝ √hMore Momentum and Collision Questions
