Small identical balls with equal charges are fixed at vertices of regular polygon with side a. At a certain instant, one of the balls is released & a sufficiently long time interval later, the ball adjacent to the first released ball is freed. The kinetic energies of the released balls are found to differ by K at a sufficiently long distance from the polygon. Determine the charge q of each ball. If it is\[\frac{1}{a}\times {{10}^{-4}}C\]. Find a. (\[k=10\text{ }Joule\], side length\[=1m\])
