47. We use the conservation of energy principle. The initial potential energy is U i = q 2 /4 πε 0 r 1 , the initial kinetic energy is K i = 0, the final potential energy is U f = q 2 /4 πε 0 r 2 , and the final kinetic energy is Km v f = 1 2 2 , where v is the final speed of the particle. Conservation of energy yields q r q r mv 2 01
