Two infinitely long parallel conducting plates having surface charge densities + and - respectively, are separated by a small distance. The medium between the plates is vacuum. If ₀ is the dielectric permittivity of vacuum, then the electric field in the region between the plates is

Options

  1. A0 volt/metre
  2. B/ 2 ₀ volt / metre
  3. C/ ₀ volt / metre
  4. D2 / ₀ volt/metre.

Correct answer

C. / ₀ volt / metre

Step-by-step solution

Electric field between the plates is aligned & = 2 ₀ - (- ) 2 ₀ & = ₀ volt / meter aligned
