a) Find the electric potential in a point at a distance p from a straight, uniformly charged wire carrying a charge per unit length 1. (10 points) b) Use the method of images to find the potential in a point P in the space surrounding a grounded, infinitely long, conducting cylinder of radius R placed in front of a straight, infinitely long and uniformly charged wire. The wire carries a charge per unit length 4. The axis of the cylinder and the wire are parallel to each other. The distance between the axis of the cylinder and the wire is d. (10 points) Hint: Look at the notes on a point charge and a grounded conducting sphere; this problem can be solved in a way very similar to the way in which we solved that problem, provided that we switch the poten- tial due to a point charge with the potential due to a line of charges discussed in part a).
