2. What is the magnitude of the electric field just inside the shell? (Express your answer with the appropriate units.)

3. What is the direction of the electric field just outside and just inside the shell?

a. radially inward just outside the shell, radially outward just inside the shell

b. radially inward just outside the shell, zero just inside the shell

c. radially outward just outside the shell, radially inward just inside the shell

d. zero just outside the shell, radially inward just inside the shell

e. zero just outside the shell, radially outward just inside the shell

f. radially outward just outside the shell, zero just inside the shell

4. What is the electrostatic potential just outside the shell, relative to zero at infinity? (Express your answer with the appropriate units.)

5. What is the electrostatic potential just inside the shell, relative to zero at infinity? (Express your answer with the appropriate units.)

6. What is the electrostatic potential at the shell's center? (Express your answer with the appropriate units.)

7. What is the electric field magnitude at the shell's center? (Express your answer with the appropriate units.)
