Two insulating plates are both uniformly charged in such a way that the potential difference between them is V2 -V1 = 20 V. (i.e. plate 2 is at a higher potential). The plates are separated by d = 0.1 m and can be treated as infinitely large. An electron is released from rest on the inner surface of plate 1. What is its speed when it hits plate 2? (e = 1.6 × 10-19 C, me = 9.11 × 10-31 kg) ?
