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.

A circular ring of radius 23.0 cm has a continuous charge distribution of -1.4 C/m. How many excess electrons
are on the ring? Write your result as multiplicative of 1018. Your result must contain one figure after the
decimal point. Maximum of 3% of error is accepted in your answer. One electron charge is -1.6x10 19 C.
A test charge of +1µC is placed halfway between a charge of +3.1µC and another of +6.5 µC separated by 10 cm. What is the magnitude of the force (in Newtons) on the test charge?
Your answer should be a number with two decimal places, do not include the unit.

(b)
Charge is an electrical property of the atomic particles of which matter consist. The
charge of an electron and a proton are equal in magnitude to 1.602 x 10-19. Calculate
the amount of charges represented by 3.28 x 10' and 5.67 x 102 of protons. State your
final answer using the standard SI prefix.
