An infinite plane electric field is a theoretical model used to describe the electric field around an infinitely large, flat surface with a uniform distribution of charge.
The electric field for an infinite plane can be calculated using the formula E = σ/2ε0, where σ is the surface charge density and ε0 is the permittivity of free space.
The direction of the electric field for an infinite plane is always perpendicular to the surface of the plane, pointing away from the plane for positive charge and towards the plane for negative charge.
As you move further away from an infinite plane, the electric field decreases in strength. However, it never reaches zero as the plane is infinitely large. The electric field also becomes more uniform and constant as you move further away.
The electric field is inversely proportional to the distance from the plane. This means that as the distance increases, the electric field strength decreases. However, the electric field is still present at any distance from the plane, no matter how far away.
