Problem 40P
Two long straight wires, carrying opposite uniform line charges ±λ, are situated on either side of a long conducting cylinder (Fig. 3.39). The cylinder (which carries no net charge) has radius R, and the wires are a distance a from the axis. Find the potential.
ANSWER:
Step 1 of 1
We have to find the potential due two long straight wires, carrying opposite uniform line charges situated on either side of a long conducting cylinder.
To find the potential , we place line charges at at and at as shown in figure below where is the horizontal axis and is the vertical axis
The total potential is given by,
