1.	A particle of mass `m` and carrying charge `-q_(1)` is moving around a charge `+q_(2)` along a circular path of radius `r` period of revolution of the charge `-q_(1)` about `+q_(2)` is
Answer» Here, force of attraction between charges = centripetal force `(1)/(4pi in_(0)) (q_(1) q_(2))/(r^(2)) = (mv^(2))/(r)` So `v = sqrt((1)/(4pi in_(0)) (q_(1) q_(2))/(mr)` Time period of revolution `T = (2pi r)/(v) = (2pi r) sqrt((4pi in_(0) mr)/(q_(1) q_(2)))` `T = sqrt((16pi^(3) in_(0) mr^(3))/(q_(1) q_(2)))`
