A horizontal circular loop of wire has radius 0.04 m. It is lowered into a liquid and a film is formed . The force due to the surface tension of the liquid is 0.033 N. Calculate the surface tension of the liquid.

Draw the neat diagrams for modes of vibration of an air column in a pipe, when (i) the pipe is open at both ends, and (ii) the pipe is closed at one end. Hence derive an expression for fundamental fre-quency in each case. A horizontal cicular loops of a wire of radius 0.02 m is lowered into crude oil and film is formed. The force due to the surface tension of the liquid is 0.0113 N . Calculate the surface a tension of the crude oil. (pi = 3.142)
