Question

Assertion: When height of a tube is less than liquid rise in the capillary tube, the liquid does not overflow. Reason: Product of radius of meniscus and height of liquid in the capillary tube always remain constant.

As h R = ρ g 2 S ​ = a finite constant. Hence when the tube is of insufficient length, radius of curvature of the liquid meniscus increases, so as to maintain the product h R a finite constant, i.e., as h decreases, R increases and the liquid meniscus becomes more and more flat, but the liquid does not overflow.
