Two very wide parallel glass plates are held vertically at a small separation d, and dipped in water. Some water climbs up in the gap between the plate. Let S be the surface tension of water `P_(0)=` atmospheric pressure, `P=` pressure of water just below the water surface in the region between the plates-

A

`P=P_(0)-(2S)/(d)`

B

`P=P_(0)+(2S)/(d)`

C

`P=P_(0)-(4S)/(d)`

D

`P=P_(0)+(4S)/(d)`
