A small piece of aluminum (atomic number 13) contains 1015 atoms. (The atomic number is the number of protons; it determines the (positive) electric charge of the nucleus and, thus, the number of electrons in a neutral atom.) If the piece of aluminum has a net positive charge of 3.0 uC, what fraction of the electrons that the aluminum had when it was neutral would have had to be lost?

A typical AA size rechargeable NiMH battery can store 1100-2100 mAh of electric charge. The small print on the battery in your hand says 1530 mAh. Can you express this amount of electric charge using the usual coulomb units? You are now charging a camera battery. The charger moves 4470 C of electric charge from the negative terminal of the battery to the positive terminal. (In reality the charger moves the negative electrons from the positive terminal to the negative terminal, but this is not important for us right now.) Assuming - incorrectly - that the voltage of the battery remains a constant 3.20 V during the whole charging process, determine the work done by the charger. And now you are charging a capacitor bank for a high-voltage physics experiment. The power supply moves Q = 8990 C of electric charge in the charging process. The supply is set to stop, when the voltage reaches AV = 710 V. How much work did the power supply perform?
Adding a proton to a nucleus The nucleus of an atom is positively charged because it consists of positively charged protons and uncharged neutrons. To bring a free proton toward a nucleus, a repulsive force F(r) = kqQ/r2 must be overcome, where q = 1.6 × 10-19 C (coulombs) is the charge on the proton, k = 9 × 109 N · m2/C2, Q is the charge on the nucleus, and r is the distance between the center of the nucleus and the proton. Find the work required to bring a free proton (assumed to be a point mass) from a large distance (r → ∞) to the edge of a nucleus that has a charge Q = 50q and a radius of 6 × 10-11 m.
