1.	A U tube is arranged such that diameter of one limb is 2D and diameter of other is D. Surface tension of water contained in the tube is T. If d is density of water, the difference in the levels of liquid is (angle of contact of liquid is zero)
Answer» `(2T)/(DDG)` `T/(Ddg)` `T/(2Ddg)` `(4T)/(Ddg)` ANSWER :A
