Problem

A singly ionized neon atom (charge

+e

, mass

3.3\times10^{-26}\,\text{kg}

) enters the region between two horizontal capacitor plates with a horizontal speed of

9.0\times10^{4}\,\text{m/s}

. The plates are 4.0 cm long, separated by 8.0 mm, and a uniform upward electric field of

1.2\times10^{4}\,\text{N/C}

fills the space between them. If the atom enters midway between the plates, calculate its vertical displacement from the entry point when it exits the plates.
