試題詳解

33. A charged conductor has the oval shape shown below. When we compare the potential at points A and B, we find that:
  
(A) V_A＞V_B
(B) V_A=V_B 
(C) V_A＜V_B
(D) V_A≤V_B
(E) we must first determine the charge distribution on the surface before we can calculate the potential difference between two points on the surface.
