Answer:
Note: When studying the following material, make sure to completely redraw the figures on your notebook and write the formulas as you proceed. This will help you learn more. Make sure to draw horizontal fraction bars when you use one.
Electric Charge and Electric Field:
In brief, electrons are negative charges and protons are positive charges. An electron is considered the smallest quantity of negative charge and a proton the smallest quantity of positive charge.
Two negative charges repel. Also, two positive charges repel. A positive charge and a negative charge attract each other (all experimentally verified.)
Point Charge: An accumulation of electric charges at a point (a tiny volume in space) is called a point charge.
Note: When an atom loses an electron, the separated electron forms a negative charge, but the remaining that contains one less electron or consequently one more proton becomes a positive charge. A positive charge is not necessarily a single proton. In most cases, a positive charge is an atom that has lost one or more electron(s).
SI Unit of Electric Charge: Coulomb
If two like point charges are separated by 1m and the repulsion force between them is 9.0x109N, each charge is called 1 Coulomb, shown as 1C. It has been shown that it takes 6.25x1018 electrons to form 1C of negative electricity.
