   E. none of the above

2. For this dipole configuration, what is the direction of the electric field at point B?

   A. up

   B. down

   C. right

   D. left

   E. none of the above

3. For this dipole configuration, what is the direction of the electric field at point C?

   A. up

   B. down

   C. right

   D. left

   E. none of the above
