| + | ===== Electrostatics ===== | ||
| + | Both positive and negative charges can move between objects. For an explanation of positive charge movement see below. | ||
| + | * Positive charges can move | ||
| + | * Protons can't move | ||
| + | * Protons are the mass while the positive charge is an electron deficiency | ||
| + | |||
| + | ==== Coulomb' | ||
| + | Coulomb' | ||
| + | * $F_e = \frac{kq_1q_2}{r^2}$, | ||
| + | * $F_e$ is the resultant force in Newtons | ||
| + | * $k$ is $9 \times 10^9$(($k$ is the constant)) | ||
| + | * $q_1$ and $q_2$ are the charges of the particles in Coulomb (C) | ||
| + | * electron = $-1.6 \times 10^{-19}$ C | ||
| + | * proton = $1.6 \times 10^{-19}$ C | ||
| + | * $r$ is the radius (distance) in meters | ||
