Infinite Planes Eletric Field Question

In summary, 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/2ε<sub>0</sub>, and its direction is always perpendicular to the surface of the plane. As you move further away from the plane, the electric field decreases in strength and becomes more uniform and constant. The electric field is also inversely proportional to the distance from the plane, meaning that as the distance increases, the electric field strength decreases, but it is still present at any distance from the plane.

Hi! I have already write everything on the pictures(In attachment), I have already circled the correct answer, however, I am not sure explain it correctly. So, can you check my explanation or question?
Thanks!

This may not help, but see figure 9 of the following,

http://phy214uhart.wikispaces.com/Gauss'+Law

If you take the configuration of figure 9 and copy it, paste it, flip it and connect the two copies together you get the same set up as your problem, the fields will be the same as your problem, fields zero outside and only nonzero between conducting planes.
 

Related to Infinite Planes Eletric Field Question

1. What is an infinite plane electric field?

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.

2. How is the electric field calculated for an infinite plane?

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.

3. What is the direction of the electric field for an infinite plane?

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.

4. What happens to the electric field as you move further away from an infinite plane?

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.

5. How is the electric field affected by the distance from the plane?

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.
