Two large parallel plates are charged such that the potential difference between them is $V_2 - V_1 = 20\ V$. Plate $2$ is at a higher potential. The plates are separated by a distance of $0.1\ m$ and can be considered infinitely large. An electron is released from rest at the inner surface of plate $1$. What is its speed when it strikes plate $2$? $(e = 1.6 \times 10^{-19}\ C, m_0 = 9.11 \times 10^{-31}\ kg)$

• A
  $2.65 \times 10^{6}\ m/s$
• B
  $7.02 \times 10^{12}\ m/s$
• C
  $1.87 \times 10^{6}\ m/s$
• D
  $32 \times 10^{-19}\ m/s$
