$3$ of the Spice Girls $($Emma$,$ Geri, and Mel C$.)$ have each placed a charge at the corners of an equilateral triangle of side $1\mathrm{.}20$ m $($see the figure$).$

Emma's charge $($Q$1)$ is $+2\mathrm{.}8$C$.$

Geri's charge $($Q$2)$ is $-7\mathrm{.}8$C$.$

Mel C$\text{'}$s charge $($Q$3)$ is $-4\mathrm{.}7$C$.$

Calculate the magnitude and direction of the net force on each of the charges due to the other $2$ charges.

$[$For instance, the net force on Geri's charge $($Q$2)$ would be due to the other $2$ charges, $($Q$1)$ and $($Q$3).]$

$($You should assume the $+$x axis points to the right, that is$,$ from Q$2$ toward Q$3.$ You should further assume the the $+$y axis points toward the top of the page.$)$
