Two identical metal spheres have charges of q1 and q2. They are brought together

Question

Two identical metal spheres have charges of q1 and q2. They are brought together so they touch, and then they are separated. Note that q1 + q2 0 C. (a) How is the net charge on the two spheres before they touch related to the net charge after they touch? The net charge before they touch is greater than the net charge after they touch. The net charge before they touch is the same as the net charge after they touch. The net charge before they touch is less than the net charge after they touch. After they touch and are separated, is the charge on each sphere the same? No, because the charge on each sphere after they touch remains what it was (q1 and q2) before they touch. Yes, the charge on each sphere is the same. No, because after they touch the charge on one sphere will be q1 + q2 and that on the other sphere will be -(q 1 + q2). Four identical metal spheres have charges of qA = -8.0 mu C, qB = -2.0 mu C, qC = +5.0 mu C, and qD = +12.0 mu C. 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 mu C? The two spheres are In a similar manner, which three spheres are brought together and then separated, if the final change on each of the three is +3.0 mu C? The three spheres are The final charge on each of the three separated spheres in part (d) is +3.0 mu C. How many electrons would have to be added to one of the three spheres to make it electrically neutral?
