4.6c. the straight line x = 6y − 4: Here, y = x/6 + 2/3, and the work is
W3 = −2 × 10−6
4.18. Find the potential at the origin produced by a line charge ρL = kx/(x2 +a2) extending along
the x axis from x = a to +∞, where a > 0. Assume a zero reference at infinity.
Think of the line charge as an array of point charges, each of charge dq = ρLdx, and each
having potential at the origin of dV = ρLdx/(4π0x). The total potential at the origin is
then the sum of all these potentials, or
160a
4.19. The annular surface, 1 cm < ρ < 3 cm, z = 0, carries the nonuniform surface charge density
ρs = 5ρ nC/m2. Find V at P(0, 0, 2 cm) if V = 0 at infinity: We use the superposition integral
form:
VP =
ρs da
4π0|r − r|
where r = zaz and r = ρaρ. We integrate over the surface of the annular region, with
da = ρdρdφ. Substituting the given values, we find
4.20. A point charge Q is located at the origin. Express the potential in both rectangular and
cylindrical coordinates, and use the gradient operation in that coordinate system to find the
electric field intensity. The result may be checked by conversion to spherical coordinates.
The potential is expressed in spherical, rectangular, and cylindrical coordinates respectively
