How does, the electric field (E) between the plates of a charged cylindrical capacitor vary with the distance r from the axis of the cylinder?

Options

  1. AE 1 r^2
  2. BE 1 r
  3. CE r^2
  4. DE r

Correct answer

B. E 1 r

Step-by-step solution

Electric field due to outer plate is zero and so the electric field due to inner cylindrical charged conductor varies inversely as the distance from the axis.
