Two capillary tube of radius r1 and r2 are put vertically one each in two liquids whose relative densities are 0.6 and 0.4 and surface tension are 60 dyne/cm and 50 dyne/cm respectively.If ratio of heights of liquid in two tube is 8:10 respectively. Find r1r2.(Assume contact angle is same in both case) |
