Two foam blocks, each with a charge of 8 microcoulombs (1 µC = 10-6 C), are both held in place 8 cm apart in the east-west direction. A foam ball with a charge 38 µC is placed 55 cm north of the foam block on the west side. Then, the ball is released, and it moves as a result of the electrostatic force produced in this system. What is the net electrostatic force (magnitude and direction) experienced by the foam ball?

Two identical conducting spheres, fixed in place, attract each other with an electrostatic force of 0.140 N when their center-to-center separation is 63.8 cm. The spheres are then connected by a thin conducting wire. When the wire is removed, the spheres repel each other with an electrostatic force of 0.0403 N. Of the initial charges on the spheres, with a positive net charge, what was (a) the negative charge on one of them and (b) the positive charge on the other?
