Centrepetal/centrefugal force on two postive charges???

Question

I have 2 charges(both positive) at a distance d...and ill give a velocity V to one of the charges in a direction perpendicular to line joining them...what is the radius of curvature at that particular instant..??(i mean--just after i give it velocity V)

can i equate mv^2/d to coloumbic force??

Answer 1

The assumption sounds reasonable to me........
