Two point charges totaling $10$ muC exert a force of size $0\mathrm{.}756$ N on one another when separated by $0\mathrm{.}5$ m$.$ What is the size of the charge on each point charge? $($Q$1$ is the smaller charge, and Q$2$ is the larger charge$)$

Q$1=$ muC

Q$2=$ muC

Hint: Treating each charge as a variable $($Q$1$ and Q$2)$ you know that Q$1+$Q$2=1$e$-05,$ use Coulombs Law to find the other equation, then you will have two equations and two unknowns and can solve for each variable.
