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.
