    (See attachment for diagram and background of this question concerning Gauss' Law) (a) What is the electric field inside the middle sheet? (b) What is the electric field between the left and middle sheets? (c) What is the electric field between the middle and right sheets? (d) What is the charge density on the sur

    Coulomb's Law and Electric Field

    Three very large square planes of charge are arranged as shown (on edge). From left to right, the planes have charge densities per unit area of -0.50 uC/m^2, +0.10 uC/m^2, and -0.40 uC/m^2. Find the total electric field (direction and magnitude) at the points A, B, C, and D. Assume the plates are much larger than the distance AD

    Electrostatics - Gauss's Law, Electrostatic Field due to spherical charge

    Hi, This problem is from a book I have, and has three parts. I have attached both the problem (p23.jpg) and the solution (a23.jpg). I've tried different approaches, but I think I'm either not using the correct formula, or not setting up the integrals correctly. I'd appreciate someone showing me how to arrive at the solu

    Spherical Electric Field

    A solid insulating sphere of radius R has an electric charge uniformly distributed throughout its volume. The charge per unit volume is p. A) Show that outside the sphere the electric field is given by E = (pR3/3E0r2), where r is the distance from the center of the sphere. B) Show that the field inside the sphere is given by (

    Problem 20: The finite size of the proton perturbs the energy of the n = 1 orbit in a hydrogen atom. (i) Given the proton to be a uniformly charge sphere of radius R = 1 fm, determine the first order energy shift, making reasonable approximations. How accurate should the first order theory be in this case? (ii) Do the

    A square conducting slab with 10m sides carries a net charge of 10 micro Coulombs. Use Gauss' law to find E inside the slab and close to its surfaces, far from the edges of the slab. The slab is placed to the right of an infinite charged nonconducting plane with charge density of 2 X 10^-6 C/m^2 so that the faces of the slab are parallel to the plane. Find the electric field on each side of the slab far from its edges and the charge density on each face.
