Water rises in a capillary tube a height h. Choose false statement regarding capillary rise from the following.

Assertion :The contact angle between water and glass is acute. Reason :The surface of water in the capillary is convex .

A capillary tube of length (i) l = 60 cm , (ii) l = 50 cm and radius r = 1//4 mm is immersed vertically into water. Find the capillary rise in both cases. Angle of contact = 0^@ . Take coefficient of surface tension as 72 "dyne"//cm, g = 1000 cm s^(-12) .

Liquid rises to a height of 2 cm in a capillary tube and the angle of contact between the solid and the liquid is zero. If the tube is depressed more now so that top of capillary is only 1 cm above the liquid, then the apparent angle of contact between the solid and the liquid is
