1.	A capillary tube of radius 'r' is lowered into water whose surface tension is 'a' and density ‘d'. The liquid rises to a height. Assume that the contact angle is Zero. Choose the correct statement(s),
Answer» MAGNITUDE of work DONE by force of surface TENSION is -`(4 pi alpha^2)/( d G)` Magnitude of work done by force of surface tension is - `(2pialpha^2)/( dg)` Potential energy acquired by the water is `(2 pi alpha^2)/( dg )` The amount of heat developed is` ( 2pialpha^2)/(d g)` Answer :A::C::D
