Two infinite parallel planes have uniform charge densities `+-sigma`. What is the electric field in the region between the planes

Two infinite parallel planes have uniform charge densities +-sigma . What is the electric field outisde the plates? In what way does the infinite extension of the planes simplify your derivation?

Two large flat parallel sheets A and B having uniform surface charge densities sigma and -sigma are held as shown in the figure graphically, represent the variation of electric field due to the two sheets as one move from the point O to P.

Two uniformly large parallel thin plates having charge densities +sigma and -sigma are kept in the X-Z plane at a distance 'd' apart. Sketch an equipotential surface due to electric field between the plates. IF a particle of mass m and charge -q remains stationary between the plates, what is the magnitude and direction of this field?

Two large flat parallel sheets A and B having a uniform charge density + sigma are held as shown in the figure. Graphically, represent the variation of electric field due to the two sheets as one moves from the point O to P.

A long charged cylinder of linear charged density lambda is surrounded by a hollow co-axial conducting cylinder. What is the electric field in the space between the two cylinders?

A sphere of charge of radius R has uniform volume charge density. The electric field due to the sphere of charge at a point
