(20 Points] DETAILS MY NOTE Shown in the figure below is a spherical shell of charge. The inner radius of the spherical shell is a and the outer radius is b. The total charge of the spherical shell is Q. There are three regions indicated in the figure and you will find the electric field in each of these regions. Region I (r>b) Region II (b>r>a) Region III Solid Insulating Spherical Shell with Charge Q Region I: (outside the shell, r > b) . What is the formula for the area of the Gaussian surface? A = What is the formula for the charge inside? Qin = . What is the formula for the electric field? E = Region II: (within the shell, b > r > a) . What is the formula for the area of the Gaussian surface? A = What is the formula for the charge inside? Qin = . What is the formula for the electric field? E = Region III: (inside the hole, r
