A fixed charge Q= +2.13 C is held fixed at the origin of an xy plane. A second charge q= +2.982 C is released from rest at the xy coordinate of (+1.15 m, +0.670 m). (a) If the mass of q is 2.70 g, what is its speed when it moves infinitely far from the origin? 5.64 m/s (b) At what distance from the origin does q attain half the speed it will have at infinity*? x m (*Please note where most of the energy exchange occurs!)
