A liquid having surface tension `T` and density `rho` is in contact with a vertical solid wall. The liquid surface gets curved as shown in the figure. At the bottom the liquid surface is flat. The atmospheric pressure is `P_(o)`.

(i) Find the pressure in the liquid at the top of the meniscus (i.e. at A)
(ii) Calculate the difference in height `(h)` between the bottom and top of the meniscus.
