Two infinite plane sheets with uniform surface charge densities are placed parallel to each other with separation d. in the regi

kupik [55]

Answer:Uniform between the plates

Explanation:

Electric Field due to infinite sheet with uniform charge is given by

$E=\dfrac{\sigma }{\epsilon _0}$

Where $\sigma$ =charge density

$\epsilon _0$ =Space Permittivity

From the formula we can see that Electric field is independent of distance of the particle, so it is uniform between the plates .
