A U-tube is made up of two capillary tubes of bores 1 mm and 2 mm. The tube is held vertically and some part of it is filled with a liquid of surface tension 0.049N .m^-1 and of zero angle of contact. If the level difference of the liquid in the two arms is 1.25 cm, then determine the density of the liquid.
