Consider two point particles that have charge $+$e$,$ are at rest, and are separated by $2\mathrm{.}5010-15$ m$.$

$($a$)$ How much work was required to bring them together from a very large separation distance?

keV

$($b$)$ If they are released, how much kinetic energy will each have when they are separated by twice their separation at release?

keV

$($c$)$ The mass of each particle is $1\mathrm{.}00$ u $(1\mathrm{.}00$ amu$).$ What speed will each have when they are very far from each other?

m$/$s
