The limbs of manometer consists of uniform capillary tubes of radii \[1.4\times {{10}^{-3}}m\]and\[7.2\times {{10}^{-4}}m\]. Find out the correct pressure difference if the level of the liquid (density\[{{10}^{3}}kg/{{m}^{3}}\], surface tension\[72\times {{10}^{-3}}N/m\]) in the narrower tube stand 0.2 m above that in broader tube.
