The general form of gauss's law describes how a charge creates an electric fleld in a material, as well as in vacuu um. e da fin where e = keo is the permittivity of the material. (a) a sheet with charge q uniformly distributed over its area a is surrounded by a dielectric. show that the sheet creates a uniform electric field with magnitude e- q/2ae this answer has not been graded yet (b) two large sheets of area a, carrying opposite charges of equal magnitude q, are a small distance d apart. show that they create a uniform electric field in the space between them with magnitude e q/ae. this answer has not been graded yet (c) assume that the negative plate is at zero potential. show that the positive plate is at a potential qd/ac. (c) assume that the negative plate is at zero potential. show that the positive plate is at a potential qd/ae. this answer has not been graded yet. (d) show that the capacitance of the pair of plates is given by c at/d kae/d.
