You have a very (infinitely) long solid conducting cylinder with length L, base radius R, and total charge +Q. (a) Use Gauss’s law to find the electric field vector inside and outside the cylinder. Explain your reasoning. You can give a verbal description of the electric field vector direction. (b) Similar to how we found the electric field outside a conducting sphere to look like that of a point particle, what does the electric field outside the cylinder look like? (c) Would the electric field inside the cylinder stay the same if the cylinder was instead insulating and uniformly charged? Explain why or why not?

Problem 18: A cylindrical capacitor is made of two concentric conducting cylinders. The inner cylinder has a radius R1 = 19 cm and carries a uniform charge per unit length of . The outer cylinder has radius R2 = 45 cm and carries an equal but opposite charge distribution as the inner cylinder. Part A: Use Gauss’ Law to write an equation for the electric field at a distance R1 < r < R2 from the center of the cylinders. Write your answer in terms of λ, r, and e0. We want to start with the equation For dA we can substitute since we need to use the lateral surface area of the cylinder and for q we can substitute since it would be the charge per unit length across the whole length of the cylinder leaving us the equation . Part B: Calculate the electric potential difference between the outside and the inside cylinders in V.

Problem 3: Imagine you have a very thin plastic hoop of diameter D, which is charged up to total net electrostatic charge Q. The hoop is thin in the sense that the plastic rod of which it is made has a diameter d D. In each case, give the magnitude and direction of the field. You might need to use words (rather than formulae) to express the direction unambiguously. Assume that there are no other charges anywhere!
Figure 1 shows four situations in which four very long rods extend into and out of the page (we see only their cross sections). The value below each cross section gives that particular rod’s uniform charge density in microcoulombs per meter. The rods are separated by either d or 2d as drawn, and a central point is shown midway between the inner rods. Rank the situations according to the magnitude of the net electric field at that central point, greatest first.
