Goal: Reason regarding electric fields

Source: 283-11, E at origin due to charged rods

For which of the configuration(s) below does the total electric field
vector at the origin have non-zero components in both the x and y

  1. 2 only
  2. 1 and 3 only
  3. 5 only
  4. 4 only
  5. 1 and 5 only
  6. None of the above



(6) Only situation 3 meets the condition. A good exercise is to have
students draw the contribution to the field at the origin due to each
rod. The contributions should have the correct relative size and
