Two large glass plates are placed vertically and parallel to each other inside a tank of water with separation between the plates equal to 1 mm. Find the rise of water in the space between the plates. Surface tension of water `=0.075Nm^-1`.

Answer

A, C

Explanation

Given `T=0.075N/m, `
`d=1mm=10^-3m`
`rho=10^3kg/m^3`
. `Now , T(2L)=[1xx(10^-3)xxh]rhog`
`rarr h=(2xx(0.075))/(10^-3xx10^3xx10)`
`h=0.015m=1.5m
