The Charge Inside a Conductor (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. Figure 1 of 1 +9 Part A What is the total surface charge 9int on the interior surface of the conductor (i.e., on the wall of the cavity)? Hints Fint -9 Submit Correct Part B What is the total surface charge dext on the exterior surface of the conductor? Hints Text +9 Submit My Answers Give Up Correct My Answers Give Up Part C What is the magnitude Eint of the electric field inside the cavity as a function of the distance from the point charge? Let &, as usual, denote 1 4nco What is the magnitude Eint of the electric field inside the cavity as a function of the distance from the point charge? Let k, as usual, denote 40 Hints 0 kq/r 2kq/r Submit Correct Part D What is the electric field Eext outside the conductor? Hints zero My Answers Give Up the same as the field produced by a point charge q located at the center of the sphere the same as the field produced by a point charge located at the position of the charge in the cavity Submit My Answers Give Up Correct Now a second charge, 92, is brought near the outside of the conductor. Which of the following quantities would change?
