Three large parallel plates have unifrom surface charge densities as shown in the figure. What is the electric field at `P`
.

Three large plates having uniform surface charge densities are shown in figure. Electric field at point 'P' will be :

Two thin infinite parallel plates have uniform charge densities + sigma and - sigma . The electric field in the space between then is
