Question

a barometer is constructed with its tube having radius 1.0mm.assume that the surface of mercury in the tube is spherical in shape.if the atmospheric pressure is equal to 76cm of mercury,what will be the height raised in the barometer tube?the contact angle of mercury with glass =135degree and surface tension of mercury=0.465N/m.density of mercury=13600kg/m^3.
