Problem

An electron enters the region between two horizontal capacitor plates midway between them. The plates are

1.0\,\text{cm}

apart, the electric field between the plates has magnitude

200\,\text{N}\!/\!\text{C}

and is directed upward, and the plates extend

0.050\,\text{m}

along the electron’s initial horizontal velocity of

3.0\times10^{6}\,\text{m}\!/\!\text{s}

. Ignore edge effects. By how much (magnitude) is the electron vertically displaced from its entry point when it leaves the space between the plates? (a)

0.20\,\text{cm}

(b)

0.050\,\text{cm}

(c)

0.49\,\text{cm}

(d)

0.98\,\text{cm}
