# Velocity of impact

Two identical metallic balls of mass $$m$$ and radius $$R$$ are initially far apart. One sphere is of charge $$Q$$ and the the other is uncharged (neutral). After they are released due to electrostatic attraction the two spheres come together and collide. If the speed $$v$$ of the balls after collision can be written as:

$v=\sqrt { \frac { (\ln(a)-b){ Q }^{ c } }{ (\ln(a))mR } }$

what is the value of $$a+b+c$$?

Details and Assumptions

The collision is perfectly elastic.
