Two spheres A and B, are placed .60 m apart. Sphere A has +3.00 uC excess charge. Sphere B has +5.00 excess charge. A third spherical charge of C of +2.00 uC is placed on the ling connecting A and B. Find the resultant force exerted by A and B on C when C is placed:

• .20 m to the left of A
• .20 m to the right of A between A and B
• exactly in the middle between A and B
