Photoelectric EffectHard
Question
A hole is made at the bottom of the tank filled with water (density 1000 k g / m3). If the total pressure at the bottom of the tank is 3 atmosphere (1atmosphere = 105 N/ m2), then the velocity of efflux is
Options
A.
B.
C.
D.
Solution
We know that velocity of efflux, v = 
At the bottom of tank pressure due to water column
= hρg = 2 × 105
⇒ gh =
⇒ v =
At the bottom of tank pressure due to water column
= hρg = 2 × 105
⇒ gh =
⇒ v =
