Problem
A point charge −q revolves around a fixed charge +q in an elliptical orbit. The minimum and maximum distances of the revolving charge from the fixed charge are r1 and r2, respectively. The mass of the revolving particle is m, where q>0. Assume no gravitational effects. Find the velocity of the revolving charge at distances r1 and r2 from the fixed charge.
