A glass rod of diameter d = 2 mm is inserted symmetrically into a glass capillary tube of radius r = 2 mm. Then the whole arrangement is vertically dipped into liquid having surface tension 0.072 Nm. The height to which liquid will rise on capillary is (Take g = 10 ms^2, density liq = 1000 kg m^3). Assume contact angle to be zero, capillary tube to be long enough
