Question

a charge q is projected from a large distance with speed v towards a fixed charged particle Q. It approaches Q upto a distance r and then returns. If closest is r/2, then projected velocity should be

Vikas TU · Accepted Answer

At large distance that is the distance approaching to infinity the potential energy assumes to be zero.Therefore, the energy theorem proves here to be:0.5mv^2 + 0 = KQq/r.................(1)for closest distance r/2,0.5mv0^2 = KQq/(r/2) => 2KQq/r...................(2)Dividing bot the eqns. we get,(v/v0)^2 = ½v/v0 = 1/root(2)v0 = v*root(2) m/s
