A particle of mass m carrying charge + q1 is revolving around a fixed charge – q2 in a circular path of radius r. Calculate the period of revolution.


Since the particle carrying posive charge is revolving around another charge,

Electrostatic force = Centrifugal force

            

                  T2 = (4πε0) r2 (4π2 mr)q1 q2

                  T =4πrπε0 mrq1 q2

where T is the period of revolution.
