Two parallel glass plates are held vertically at a small separation d and dipped in a liquid of surface tension T , the angle of contact `theta =0^@` and density `rho ` . The height of water that climbs up in the gap between glass plates is given by

A

`2T//drhog`

B

`T//2drhog`

C

`T//drhog`

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
A
Upward force due to surface tension is balanced by the weight of the liquid which rises in the gap, so `2T.b =bdhrhog`
`"where, b = width of the plates"therefore h=(2T)/(drhog)`
