Part B (Figure 1)A spherical cavity is hollowed out of the interior of a neutral conducting sphere. At the center of the cavity is a point charge, of positive charge q. What is the total surface charge qext on the exterior surface of the conductor? View Available Hint(s) ? Text = Part C What is the magnitude Eint of the electric field inside the cavity as a function of the distance r from the point charge? Let k, as usual, denote ATTen View Available Hint(s) Part G Oo The electric field within the cavity, Ecav: O kq/72 O would change O 2kq/72 O would not change Part D What is the electric field Eext outside the conductor? Part H View Available Hint(s) The electric field outside the conductor, Eext: O zero O the same as the field produced by a point charge q located at the center of the sphere O would change the same as the field produced by a point charge located at the position of the charge in the cavity O would not change
