Four identical metal spheres have charges of qA = -8.0 μC, qB=-2.0 μC, qC=+5.0 μC, and qD=+12.0 μC.

(a) Two of the spheres are brought together so they touch, and then they are separated. Which spheres are they, if the final charge on each one is +5.0 μC?

(b) In a similar manner, which three spheres are brought together and then separated, if the final charge on each of the three is +3.0 μC?

(c) The final charge on each of the three separated spheres in part (b) is +3.0 μC. How many electrons would have to be added to one of these spheres to make it electrically neutral?

You have two identical metal spheres, one with a -2.0-µC charge and one with a 20.0-µC charge, located 5 cm apart. They are brought into contact with each other, which distributes the charge evenly over the available surface area, and then moved back to their original positions. Determine the ratio of the magnitude of the new electric force between them to the original electric force between them.
