In the bottom of a vessel with mercury there is a round hole of diameter `d=70mum`. At what maximum thickness of the mercury Layer will the liquid still not flow out through this hole ? `[rho_("mercury")=13600(kg)/(m^(3))]`

A

11 cm

B

21 cm

C

42 cm

D

32 cm

Text Solution

Verified by Experts

The correct Answer is:
B
`h=(4T)/(rhogd)`.
As the height increases the radius of curvature of the liquid layer decreases.
