Two thin uniformly charged rods, each with length LL and total charge +Q+Q, are parallel and separated by a distance aa. The first rod has one end at the origin and its other end on the positive yy-axis. The second rod has its lower end on the positive xx-axis.
******************
Suppose LL = 50.0 cmcm, aa = 10.0 cmcm , QQ = 10.0 μCμC, and the mass of each rod is mm = 500 gg. If the two rods are released from the original configuration, they will fly apart and ultimately achieve a particular relative speed. What is that relative speed?
Express your answer with the appropriate units.
