Textbook Question
Chapter 21, Problem 57P
We know that the negative charge on the electron and the positive charge on the proton are equal. Suppose, however, that these magnitudes differ from each other by 0.00010%. With what force would two copper coins, placed 1.0 m apart, repel each other? Assume that each coin contains 3 × 1022 copper atoms. (Hint: A neutral copper atom contains 29 protons and 29 electrons.) What do you conclude?

Because the charges on the electron and proton have the same absolute value, atoms are electrically neutral. Suppose that this is not precisely true, and the absolute value of the charge of the electron is less than the charge of the proton by 0.00100%. Estimate what the net charge of this textbook would be under these circumstances. Make any assumptions you feel are justified, but state clearly what they are. (Hint: Most of the atoms in this textbook have equal numbers of electrons, protons, and neutrons.) What would be the magnitude of the electric force between two textbooks placed 5.0 m apart? Would this force be attractive or repulsive? Discuss how the fact that ordinary matter is stable shows that the absolute values of the charges on the electron and proton must be identical to a very high level of accuracy.
(Figure 1) shows five electric charges. Four charges with the magnitude of the charge 2.0 nC form a square with the size a = 1.5 cm . Positive charge with the magnitude of q = 2.5 nC is placed in the center of the square. What is the direction of the force on the 2.5 nC charge in the middle of the figure due to the four other charges? Express your answer in degrees to two significant figures.
Three charges Q1, Q2 and Q3 are arranged in a straight line. The force of attraction between Q1 and Q2 is 2.589 N and the distance between charge 2 and charge 3 is 4/3 meters. If the Net force experienced by charge 3 is 2.670 N, what is the magnitude and polarity of charge 1 if the distance between charge 1 and charge 2 is 1/3 meters? What is the magnitude and polarity of charge 3 if the distance between charge 1 and charge 2 is 1/3 meters?
