- Consider a cube of side a with 8 charges (4 with charge +e and 4 with charge -e) at the 8 corners. a Since there are a total of 8 charges, there are 28 pars. This may seem like a lot of terms to add, but many of the terms are identical. For example, 12 of the pairs are of opposite sign and separated by an edge of the cube (a distance a). Also, 12 of the pairs are of the same sign and separated by a diagonal of one face (a distance √2 a). Finally, 4 of the pairs are of opposite sign and separated by a diagonal of the cube (a distance √3 a). Calculate the total electrostatic potential energy of this configuration by summing over all the pairs of charges. Give your answer as the numerical coefficient of the following expression U= 4²4 Give your answer to 4 significant figures, and make sure you include the proper sign.Two concentric cylinders are shown in the figure. The inner cylinder is a solid insulator of radius a, length L, and carries a charge -2 uniformly distributed over its volume. The outer cylinder is a cylindrical, conducting shell, of also length L,inner radius b, and outer radius c that carries a net charge +2Q. The space between a and b is filled with air. No other charges are present. Let r denote the distance from the center of the arrangement. Express all your answers in terms of all or any of the quantities M, Q, L, a, b, c, r. and any fundamental constants ONLY. Ignore edge effects. L A. Determine the charge on the inner and outer surfaces of the cylindrical shell (S2 and S3). B. Use Gauss law to determine the magnitude of the electric field as a function of distance from the center r for: iv) r>c' a. i) rA cubic space (2m on each side) contains positively charged particles. Imagine that the space is surrounded by a Gaussian surface of the exact same dimension as the cube and that the E-Field caused by the charges is normal to the faces of the Gaussian cube. If the E-field at each surface has a magnitude of 760 N/C, determine the number of charges per unit volume in the space described and find the volume charge density ρ.Can someone please help with the following questions?
