Net Force on a Charge Between Charges

EANDM-O73ENZ

Two positive charges $Q=1\mu C$ are held at a fixed distance $d=10$ cm apart. A particle of mass $m=2$ g and charge $-q=-2\mu C$ is placed midway between them and given a small displacement $x=1$ mm in the direction perpendicular to the line joining the two positive charges, and released.

What is the net force acting on the particle?
