From a water tap liquid comes out in form of cylinder As water moves down radius of that cylinder decreases Consider a very small element of height h and radius R due to small height radius is assumed to be constant Ch This element is given in the diagram An imaginary cross section ABCD divides this element in two equal semi cylinders S is surface tension of liquid Now choose correct statement s B D A Surface energy of this elementary cylinder is S 27Rh 2 R 2S B Pressure inside the cylinder is more than atmospheric pressure by R C Force exerted by one half cylinder on another half cylinder due to surface tension is 2Sh
