Ch. 5: Electrostatics & Magnetism Flashcards
1
Q
Coulomb’s Law equation
A
Fe = kq1q2 / r^2
Fe = electrostatic force
k = coulomb’s constant (9x10^9)
q1 and q2 = magnitudes of charges
r = distance between charges
2
Q
Electric Field equation
A
E = Fe/q = kQ/r^2
Q = source charge q = positive test charge
electric field lines point from positive to negative
