As shown in the figure, two large conducting plates are positioned parallel to each other and carry equal and opposite charges with surface density . Determine the electric field to the left of the plates.

Options

  1. A2 ₀
  2. B0
  3. C₀
  4. D2 ₀

Correct answer

B. 0

Step-by-step solution

Let the surface charge density on the positive plate be + and on the negative plate be - . The electric field produced by a large plane sheet of charge with surface charge density is given by E = 2 ₀ . For a point to the left of both plates: The electric field due to the positive plate is directed towards the left (away from the plate) with magnitude E_+ = 2 ₀ . The electric field due to the negative plate is directed towards the right (towards the plate) with magnitude E_- = 2 ₀ . Since these two fields are in opp
