Part A

A positive point charge $q_1=2\mathrm{.}5C$ is located at

$x=0,y=0\mathrm{.}30m,$ a negative point charge

$q_2=-2\mathrm{.}5C$ is located at $x=0,y=-0\mathrm{.}30m.$ A

third point charge $Q=5\mathrm{.}0C$ is located at

$x=0\mathrm{.}40m,y=0.$

What is the magnitude of the total electric force that charges $q_1$ and $q_2$ exert on charge $Q?$
