If three uncharged styrofoam balls are placed together and agitated so that one gains +3 C of charge and another gains +4 C of charge, how much charge must there be on the third one? O+7C O+1 C OOC O-7C

Step 1
Initially, the balls are uncharged, so the total charge is 0. $q_1 + q_2 + q_3 = 0$ Show more…

An experiment; three identical metal balls (A, B, and C) are each held with insulating supports. Each contains no charge initially and all are held at a large distance from each other. Ball A is then charged with charge +Q. It is then brought into contact with ball B and then placed back at its original position. Then ball B is brought into contact with ball C, and subsequently returned to its original position. Finally, ball C is brought into contact with ball A and then replaced to its original position. What is the final charge on all three balls? [Extra credit point: If you were to repeat the above process a very large number of times, what would the ultimate amount of charge be on each sphere?]
Urvashi A.
Five styrofoam balls are suspended from insulating threads. Several experiments are performed on the balls; and the following observations are made: I. Ball A attracts B and A repels C. II. Ball D attracts B and D has no effect on E. III. A negatively charged rod attracts both A and E. What are the charges, if any, on each ball? A. +, –, +, 0, + B. +, –, +, +, 0 C. +, –, –, 0, 0 D. –, +, –, 0, 0

E2. Two identical brass balls mounted on wooden posts initially have different amounts of charge: one -7 μC and the other -21 μC. The balls are allowed to touch and then are separated again. What is the final charge on each ball?
