This Homework was sent to me to review for the test. I need step by step answers in a way i can understand what is going on.

Open-Response Homework 4: Gauss' Law Il Problem 1 Consider the situation shown in the figure. There is a uniform charge density o in the y-z plane. There are also charges elsewhere outside the picture. The net field resulting from all the charges E E. has the form E- = 100 2x + 50dy in the region > 0. What is the value of the surface charge density o in the y-z plane? n Problem 2 A cylinder of radius 6 cm carries a uniform surface charge density o = 7 x 10-C/m". A uniform line charge runs down the axis of the cylinder with linear charge density, X = -0.1,C/m. Work the problem starting with Gauss Law. Compute the electric field everywhere. Problem 3 A point charge is enclosed by a spherical Gaussian surface. First, the point charge is located at exactly the center of the Gaussian sphere. Using this configuration, the electric flux through the Gaussian surface and the electric field at each point on the surface are found. (a) If the point charge is moved so that it is no longer located at exactly the center of the Gaussian sphere, is the electric field at each point on the Gaussian surface the same as it was before the charge was moved? (b) If the point charge is moved away from the center of the sphere, is the electric flux through the Gaussian surface the same as it was before the charge was moved
