There are 3 charges: +q, -2q, and +q on the z axis, with -2g at the origin, and +q at z = a and z = -a as shown in the figure below. This system can be considered as a linear quadrupole, oriented along z axis, because the total charge is zero and the dipole moment is zero (consider it as two dipoles (+q, -q) pointing in opposite directions). Using the principle of superposition, the exact electric potential of this quadrupole is written as: V (r, 0) Vr? +a²–2arcose V ta²+2arcos0 Find the approximate electric potential of this quadrupole at the large distance r from it. -29 +q

Two spherical, hollow conductors are concentrically nested as shown in the cross-sectional diagram below and electrically isolated from each other. A net charge of -3 nC is divided between the conductors, with a total of -12 nC on the inner conductor and +9 nC on the outer one. The charges are, of course, free to move between the surfaces within each shell but cannot move from one shell to the other. The inner conductor has an inner radius of a=2 cm, outer radius of b=3 cm. The outer conductor has an inner radius of c=6 cm, an outer radius of d=8 cm. a (a) In equilibrium, all of the excess charge is found on the surfaces. Why is there no charge between a and b, nor between c and d? (b) Determine the net charge on each surface (ie how much charge is there at r = a, at r = b, at r = c and at r= = d).
