Question

A particle of mass m and carrying charge -q₁_{is moving around a charge:+q}_{2 along a circular path of radius r.find period of revolution of charge}

Open in App

Solution

find the force between the two charges using coulumb force formula.

see that force is attracting. also charge -q1 is revolving

thus it is the case of circular motion with that force acting as centripital force.

equate it to mw²r (centripital force on body of mass m and revolving with w angular speed)

find w.

I have done it here for you.
