You have three identical metal spheres that have different initial net charges. Sphere A has a net charge of +5Q; sphere B has a net charge of −2Q; and sphere C has a net charge of +8Q. You first touch sphere B to sphere A, and then separate them; you then touch sphere A to sphere C, and then separate them; and finally you touch sphere C to sphere B, and then separate them. (a) Assuming no charge is transferred to you, what is the total combined charge on the three spheres at the end of the process? Q (b) What is the charge on sphere A at the end of the process? Q (c) What is the charge on sphere B at the end of the process?

Assume that two of the electrons at the negative terminal have attached themselves to a nearby neutral atom. there is now a negative ion with a charge -2e at this terminal. what are the electric potential and electric potential energy of the negative ion relative to the electron? the electric potential and the electric potential energy are both twice as much. the electric potential is twice as much and the electric potential energy is the same. the electric potential is the same and the electric potential energy is twice as much. the electric potential and the electric potential energy are both the same. the electric potential is the same and the electric potential energy is increased by the mass ratio of the oxygen ion to the electron. the electric potential is twice as much and the electric potential energy is increased by the mass ratio of the oxygen ion to the electron.
