Web9 May 2024 · We can make the relationship between potential difference and the magnetic field explicit by substituting the right side of Equation 2.5.1 into Equation 2.5.2, yielding. ΔW ≈ q[v × B(r)] ⋅ ˆlΔl. Equation 2.5.3 gives the work only for a short distance around r. Now let us try to generalize this result. WebPotential Charge Energy q. The potential energy of a charge q located at a distance r from a stationary charge Q is equal to the ratio of the product of the electrostatic constant k and charges q and Q to the distance r between charges, where k = 8.9875517873681764 × 109. Potential energy is positive if the charges are repelled from each other ...
