Question

A positive point charge is released from rest at a distance r 0 from a positive line charge with uniform charge density. The speed ( v ) of the point charge, as a function of instantaneous distance r from line charge, is proportional to, v ∝ r r 0, v ∝ ln ⁡ r r 0, v ∝ ln ⁡ r r 0, v ∝ e + r r 0
