The potential is known to vary with radial coordinates as V = 500p^2. The region 0.1 < p < 0.3 m is free space, (but may contain a charge density) while the surfaces at p = 0.1 and p = 0.3 m are good conductors.
EXPLAIN EACH STEP AND NAME ANY PARTICULAR LAW OR RELATION OR VECTOR OPERATION THAT YOU USE.
a) Determine the surface charge density on each conductor.
b) What is the total charge in a 1 meter length of the free space charge?
