Q)
Two insulating plates are both uniformly charged in such a way that the potential difference between them is $V_2 -V_1 = 20 V$.(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 ? <br> ($e = 1.6 \times 10^{-19} C, m_0 = 9.11 \times 10^{-31} kg$) <br>
