I read from a website that the electric field is independent of the separation between the plates if the separation is negligibly small. But how to derive this?
"Deriving Electric Field Independence on Negligible Separation" refers to the process of mathematically determining the electric field strength between two charged particles when the distance between them is so small that it can be considered negligible or insignificant.
Negligible separation is important because it allows us to simplify the calculation of electric field strength between two particles. It is often used when the distance between the particles is very small compared to the size of the particles, making the calculation more manageable.
When the distance between two charged particles is negligible, the electric field strength becomes independent of the separation distance. This means that the electric field strength will remain the same regardless of how close or far apart the particles are.
The equation for deriving electric field independence on negligible separation is E = (kq)/d^2, where E is the electric field strength, k is the Coulomb's constant, q is the charge of the particles, and d is the distance between the particles.
No, the concept of negligible separation can only be applied to calculations involving two point charges. If the charges are not point charges or if the distance between them is not small enough to be considered negligible, this concept cannot be applied.
