QUESTION If the charge at the center of the sphere is made positive, how is the charge on the inner surface of the sphere affected? (Select all that apply.) The absolute value of the charge on the inner surface would increase. The absolute value of the charge on the inner surface would remain the same. The charge on the inner surface would be negative. The charge on the inner surface would be positive. The absolute value of the charge on the inner surface would decrease. There would be no net charge on the inner surface.
