Surface tension of a soap solution is T...

Surface tension of a soap solution is T. There is a soap bubble of radius r. The amount of charge that must be spread uniformly on its surface so that its radius becomes 2r is `(8 pi r^(2))[varepsilon_(0)((KT)/(r)+7P_(0))]^(1/2)]` Atmospheric pressure is `P_(0)`.Assume that air temperature made the bubble remains constant.Find value of K
