Question

if h is the height rise of liquid in long capillary of tube of radius r,then which of the following relation will be correct for a given liquid?? 1. hr^2=constant 2. h/r^2 3.h/r= constant 4. hr = constant​

Answer 1

Answer:

When water rises in a capillary tube of radius r to a height h, then its potential energy is U. If capillary tube of radius "2r' is dipped in same water then potential energy of water is U2.
