Let a particle of charge having velocity approaches upto the closest distance and if the velocity becomes , the closest distance will be .
The law of conservation of energy yields, kinetic energy of particle=electric potential energy between them at closest distance of approach.
or
or .....(i)
constant
and .....(ii)
Dividing Eq. (i) by Eq. (ii), we get
