The radii of two columns in a `U` tube are `r_(1) and r_(2) (r_(1) gt r_(2))`. A liquid of density `rho` is filled in it. The contact angle of the liquid with the tube wall is `theta`. If the surface tension of the liquid is T then plot the graph of the level difference (h) of the liquid in the two arms versus contact angle `theta`. Plot the graph for angle `theta` changing from `0^(@) to 90^(@)`. Assume the curved surface of meniscus to be part of a sphere.
