A glass `U-`tube is inverted with open ends of the straight limbs, of diameters `0.5 mm` and `1.0 mm` below the surface of water in a beaker. The air pressure in the upper part is increased until the meniscus in one limb is level with the water outside. Find the height `(cm)` of water in the other limb in nearest integer. : (Density of water is `10^(3)Kg//m^(3)` and surface tension of water is `7.5 xx 10^(-2)N//m`. Take contact angle `theta = 0^(@)`)
