A beam of electrons of mass $m_c$ is deflected vertically by the uniform electric field between two oppositely charged, parallel metal plates. The plates are a distance d apart, and the potential difference between the plates is $\Delta V$. (a) What is the direction of the electric field between the plates? (b) If the y-component of the electrons' velocity as they leave the region between the plates is $v_y$, find an expression for the time it takes each electron to travel through the region between the plates in terms of $\Delta V , v _ { y } , m _ { \mathrm { e } } , d$, and e. (c) Does the electric potential energy of an electron increase, decrease, or stay constant while it moves between the plates?
