Two particles, one with charge $-2\mathrm{.}93C$ and one with charge $3\mathrm{.}55C,$ are $5\mathrm{.}09cm$ apart.

What is the magnitude $|vec(F)|$ of the force that one particle exerts

on the other?

$|vec(F)|=$

Two new particles, which have an identical positive charge $q_3,$ are placed the same $5\mathrm{.}09cm$ apart, and the force between them is

measured to be the same as that between the original particles.

Determine $q_3$ in microcoulombs.
