In figure two positive charges- -q-2- and -q-3- fixed along the y-axis- exert a net electric force in the -x direction on a charge -q-1- fixed along the x-axis- If a positive charge Q is added -x-0- the force on -q-1-shall increase along the positive x-axisshall decrease along the positive x-axisshall point along the negative x-axisshall increase but the direction changes because of the intersection of Q with -q-1- and -q-3-

Since positive charge q2 and q3 exert a net force in the -X direction on the charge Q1 fixed along the X-axis- the charge q1 is negative as shown in figure- Obviously- due to addition-xA0-of positive charge Q ad -x-0- the force on -x2212-q shall increase along the positive X-axis-

Since positive charge q2 and q3 exert a net force in the +X direction on the charge Q1 fixed along the X-axis, the charge q1 is negative as shown in figure. Obviously, due to addition of positive charge Q ad (x,0) the force on −q shall increase along the positive X-axis.
