A charge particle 'q' is shot towards another charged particle 'Q' which is fixed, with a speed 'v'. It approaches 'Q' upto a closest distance r and then returns. If q were given a speed of '2v' the closest distances of approach would be (neglect otherforces except electric forces) (1) r/ 2 (2) 2r (3) r (4) r/ 4
