A glass rod of diameter d_1=1.5 mm is inserted symmetrically into a glass capillary with inside diameter d_2=2.0 mm. Then the whole arrangement is vertically oriented and brought in contact with the surface of water. To what height (in cm) will the liquid rise in the capillary ? Surface tension of water =73xx10^-3 N.m^-1.
