(a) One of the — Q charges in Figure 20-26 is given an outward "kick" that sends it off with an initial speed V0 wIn le the other three charges are held at rest. If the moving charge has a mass m, what is its speed when it is infinitely far from the other charges? (b) Suppose the remaining — Q charge, wIn ch also has a mass m, is now given the same initial speed, V0. When it is infinitely far away from the two +Q charges, is its speed greater than, less than, or the same as the speed found in part (a)? Explain.
