A $+3$C test charge is placed at the origin $($x$,$y coordinates $0$ m$,0$ m$)$ of a $2-$ dimensional plane. What is the magnitude and direction of the total force acting upon this test charge given that there is a $-2$C charge placed at $(2$ m$,-2$ m$)$ and a $-2$C charge placed at $(2$ m$,2$ m$)?$ Assume that the charges lie in free space
