Two insulating plates are both uniformly charged in such a way that the potential difference between them is V2-V1=20V. (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 x 10-19C, m0=9.11 x 10-31kg
