Consider the arrangement of three identical small charged spheres, each of mass $3\mathrm{.}2$g

and charge $49\mathrm{.}9$nC

$,$ as shown in the figure. The charges are positioned at the vertices of an equilateral triangle with side lengths of $37\mathrm{.}1$cm

If these spheres are released from rest at precisely the same time, how fast, in meters per second, will they be moving when they are infinitely far away from each other?
