Question

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

Options:

Answer:

C

Solution:

Electric field between the plates is $= \frac{σ}{2 ε _{0}} - \frac{( - σ )}{2 ε _{0}} = \frac{σ}{ε _{0}} volt / meter$
