Two identical conducting spheres, fixed in place, attract eachother with an electrostatic force of -0.6883 N whenseparated by 50 cm, center-to-center. The spheres are then connected by a thin conducting wire. When the wire is removed, thespheres repel each other with an electrostatic force of 0.1231N. What were the initial charges on the spheres? Since oneis negative and you cannot tell which is positive or negative,there are two solutions. Take the absolute value of the charges and enter the smaller value here.
