A metal cube is perforated to form a spherical cavity as shown in the figure. In the cavity, hang a point charge q = +2 x 10-7 C, so that the charge is exactly at the center of the cavity. a. If the radius of the cavity is a = 5 cm , what is the electric field strength inside the cavity, 3 cm from the point charge at the center of the cavity? b. What is the electric field strength at a point in the cube outside the cavity?
