Two insulating plates are both uniformly charged in such a way that potential difference between them is (V2 -V1 = 20 V) (i.e., plate 2 is at higher potential). The plates are separated by d = 0.1 m and can be treated as infintely large. An electron is released from rest on the inner surface of plate 1. What is its speed when it hits plate 2 ?
