A problem by Bidesh Sengupta
A container of width 2a is filled with liquid. A thin wire of mass per unit length λ is gently placed over the liquid surface in the middle of the surface. As a result the liquid surface gets depressed by a distance y (y << a).Determine the surface tension of the liquid. a=0.2m λ= 1 kg/m y= 0.002m g= 10m/s^2
