Question

Two infinitely long parallel conducting plates having surface charge density +σ and -σ respectively, are separated by a small distance. The mediun between the plates is vacuum. If ε0 is the dielectric permittivity of vacuum the plates is:

Options

A.0 volt/m
B.σ / 2ε0 volt/m
C.σ / ε0 volt/m
D.2σ / ε0 volt/m

Solution

         
Field at P due to plate, A =
Field at P due to plate, B =
Both are acting in the same direction so, Total field =
