The class is about Electricity and Magnetism. The website wants exactly the perfect answer and in the same metric system units that are stated on the calculators that are on the picture for the question, if not, it'll mark it wrong.

A solid metal cube of side length L has a spherical cavity of radius r at its center. At the center of the cavity there is a positive point charge O. The metal cube carries a net positive charge q (not including (). a. What is the total charge on the surface of the spherical cavity? Express your answer in terms of the given variables and (if needed) 6p. Dinner = abc sin(x 1X10" Submit Reset Reset All .Draw an imaginary Gaussian surface within the conductor that encloses the cavity. What is the electric field at points on the Gaussian surface, and what does this tell you about the total charge enclosed within the Gaussian surface? -See Section 22-3 for a discussion of conductors. b. What is the total charge on the outer surface of the cube? 0. Router = abc sin(x JX10" Submit Reset Reset All .The total charge on the conducting cube is constant
