WebFig. 26–2. A charge moves on an arbitrary trajectory. The potentials at (x, y, z) at the time t are determined by the position P ′ and velocity v ′ at the retarded time t − r ′ / c. They are conveniently expressed in terms of the coordinates from the “projected” position Pproj. (The actual position at t is P .) WebSince dQ dQ is a point charge we know the magnitude of the electric field, dE = \dfrac {1} {4\pi\epsilon_0}\,\dfrac {dQ} {l^2} dE = 4πϵ01 l2dQ. This electric field equation is identical to Coulomb’s Law, but with one of the charges (q) (q) set to a value of 1 1.
