Formulas and Key Relations

2. Potential and Potential Energy

W_RP = ∫_R^P F_ext · dr

ΔU = U_P - U_R = W_RP

V(r) = Q / (4πε0 r)

V = (1 / 4πε0) (q1 / r1P + q2 / r2P + ... + qn / r nP)

Potential energy of charge in external field = qV(r)

3. Dipole Potential and Dipole Energy

U(θ) = -p · E

τ = p × E

Potential on dipole axis = ± (1 / 4πε0) (p / r^2)

4. Equipotential Surfaces and Field

|E| = -δV/δl = +|δV|/δl

Potential Due to Dipole and a System of Charges

Dipole moment has magnitude p = q × 2a and points from -q to q.

Key relations

For a point charge Q at distance r, V(r) = Q/(4πε0r).

The total potential is the algebraic sum of potentials due to individual charges: V = (1/4πε0)(q1/r1P + q2/r2P + ... + qn/rnP).
