I'm looking for a equation (or equations) needed to calculate the electric field between to plates with the same charge. For example, two plates with positive charge.

Any help is appreciated.

In summary: No field lines from either plate will terminate on the other. Field lines are between surfaces of different charge only. Being able to draw the field of both plates? I don't think there are equations, just guidelines for understanding. All lines begin perpendicular and can not intersect.Thanks for your answer. Actually I'm not really familiar with these concept. So sorry if my questions look really basic.So, like you said, we don't have any field. now, imagine a positively charged particle passes through two positively charged plates. How can I write the energy balance for the motion of particle?Thanks.Oh man, you're going down a path I avoid like the plague. I hate those equations

Well, you don't need the plates there. Just look at formulas for particles moving perpendicular to an electric field.

Can you give me a hint as to what you're doing? I understand privacy but I think this could be much easier.

Thanks Samon4.

This is the problem ( V is velocity, "a" is acceleration)

If there's nothing else in the universe, there's no field between two plates with the same charge.

Can you (1) figure out the field due to a single plate, and (2) use the principle of superposition when there are two plates?sina_mech said:

An electric field between two plates with the same charge is a region in space where an electric force is exerted on charged particles. In this case, the two plates have equal and opposite charges, creating an electric field between them.

The electric field strength between two plates with the same charge is calculated using the formula E = Q/Aε, where E is the electric field strength, Q is the charge on the plates, A is the area of the plates, and ε is the permittivity of the medium between the plates.

The direction of the electric field between two plates with the same charge is from the positive plate to the negative plate. This is because the electric field lines always point from positive charges to negative charges.

The electric field strength between two plates with the same charge is inversely proportional to the distance between the plates. This means that as the distance between the plates increases, the electric field strength decreases.

Yes, the electric field between two plates with the same charge can be made uniform by ensuring that the plates are parallel and the distance between them is constant. This will result in the electric field having the same strength and direction at all points between the plates.
