Question

Two separate parallel long (infinitely long) wires in air and parallel to the ground are separated by a distance D = 1.0m. They are made of conducting material. Each has a radius a 2.0cm, and opposite/equal amounts of charge density (λι = Qit/L and Az = QL). The voltage difference between the wires is ΔΙ. = 440 Vlts. Let's label this pair as pair A (a) What is the potential difference between a pair of long telephone wires (pair B) a distance (w15c, parallel to the ground, and located h 0.60m below pair A. Assume that the electric fields produced by the wires in pair A are unaffected by the telephone wires. Also assume that the charge distributionin each wire of pair A is cylindrically symmetric about the centre. (b) Explain why the second assumption in part (a) oversimplifies the problem (c) If the electric potential of the negatively charged wire is set to zero, what is the electrical potential at a distance infinitely far away (very far away) from the wires.
