A fixed charge Q= +3.79 µC is held fixed at the origin. A second charge q= +3.79 µC is released from rest at the position (1.15 m, 0.350 m)
a) If the mass of q is 1.10 g, what is its speed when it moves infinitely far from the origin?
b) At what distance from the origin does q attain half the speed it will have at infinity?
