A negative test charge −q is released from rest at a distance r away from a sphere of charge +Q, and a distance 2 r away from a sphere of charge +2Q. The charged spheres are fixed in place. System of charges arranged in a horizontal line. Test charge minus Q is in the middle position. Charge plus Q located a distance R to the left. Charge +2Q located a distance 2R to the right. In what direction does the test charge move immediately after being released?
