Formulas and Key Relations
1. Electric Charge and Basic Properties
q = ±ne
e = 1.6 × 10^-19 C
qv = qs
3. Electrostatic Induction and Electroscope
q_i = -q(1 - 1/K)
1 C = 1 A-s
4. Coulomb’s Law and Constants
F = kq1q2/r^2
F = (9.0 × 10^9)q1q2/r^2 newton
F = (1/4πε0)·q1q2/r^2
F = (1/4πε0K)·q1q2/r^2
F12 = (1/4πε0)·(q1q2/r^3)·r12(vector)
1 coulomb = 1 ampere × 1 second.
