The Electricity and Magnetism Test consists of 16 questions. Correct answers are found through links located at the end of each question. Answers for problems will have an additional link to a problem solution screen. If you bring up such a solution screen be sure to close it by clicking the button in the upper left corner or upper right corner. The answer section is formatted for on-screen use, not printing, and will waste a lot of paper if printed directly.
Charge is a fundamental property of an electron.
The negative charge on an electron is as fundamental to the electron as gravitational attraction is to masses. You cannot separate gravity from masses and you cannot separate charge from an electron. Objects that are electrical nonconductors. Electric charges on objects result from the gain or loss of electrons. Electrons do not move easily through nonconductors so electrons can be added and the charge tends to remain, giving the object an electrostatic charge.
