Question
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, m0 = 9.11 × 10-31 kg)
(e = 1.6 × 10-19 C, m0 = 9.11 × 10-31 kg)
Options
A.2.65 × 106 m/s
B.7.02 × 1012 m/s
C.1.87 × 106 m/s
D.32 × 10-19 m/s
mv2 = e(V2 - V1)
= 2.65 10 m / sMore Atomic Structure Questions
