- Problem 13: Each plate of a parallel-plate capacitor has an area of A = 0.61 m2. The plate separation is 3.0 mm, and one of these plates is shown in the figure. It carries a charge of Q = 2.9 μC, which is concentrated on its inner surface. Imagine a cylindrical Gaussian surface, of radius r = 0.012 m, whose axis is perpendicular to the plates. One end of the cylinder is inside the plate shown and the other end is located between the plates. Both ends are parallel to the plates. Part (a) What is the flux through surface 1 Φ1, in newton meters squared per coulomb? Part (b) What is the flux through surface 2 (the outside of the cylinder not including the ends), in newton meters squared per coulomb? Part (c) What is the flux through surface 3 Φ3, in newton meters squared per coulomb? Part (d) Using all of your results, input an expression for the field within the capacitor E, in terms of the quantities given in the problem.5.
