The field between two plates of a parallel plate capacitor of separation d is 1NC-1. A charge +Q, of mass m, is placed at distance l from +ve plate, with a velocity v towards it. The charge.
(a) will migrate to the –ve plate always
(b) will migrate to the +ve plate
(c) will oscillate about a mean position
(d) will migrate to the +ve plate if v exceeds critical values
