47. We use the conservation of energy principle. The initial potential energy is Ui= q2/4πε0r1, the initial kinetic energy is Ki= 0, the final potential energy is Uf= q2/4πε0r2, and the final kinetic energy is Kmvf=122, where vis the final speed of the particle. Conservation of energy yields qrqrmv201
