[Solved] Four point charge, each of +q, are rigidly fixed at the four corners of a square planar soap film of side 'a'. The surface tension of the soap film is \\gamma. The system of charges and planar film are in equilibrium, and a = k\\left[\\frac{q^2}{\\gamma}\\right]^{\\frac{1}{N}}, where 'k' is a constant. Then N is - - JEE (Advanced) 2011 Paper-1
