A vessel whose bottom has round holes with diameter of 1 mm is filled with water Assuming that surface tenstion acts only at holes, then the maximum height to which the water can be filled in vessel without leakage is (given surface tension of water is `75xx10^(-3)N//m)` and `g=10m//s^(2)`

Options

A. 3 cm
B. 0.3 cm
C. 3 mm
D. 3 m

Answer

A

Explanation

Gauge pressure `=` excess pressure above the maniscus
`implieshdg=(2T)/(r)=h=(2T)/(r)impliesh=(2T)/(rdg)`
