Question

What are the cases of neutral zone between two charged plates?

A) No cases, the neutral zone doesn't exist.
B) The neutral zone exists when the plates have equal and opposite charges.
C) The neutral zone exists when the plates have the same charge.
D) The neutral zone exists when one plate is charged, and the other is not.

Answer 1

The neutral zone between two charged plates exists when the plates have equal and opposite charges.

Step-by-step explanation:

The correct answer is B) The neutral zone exists when the plates have equal and opposite charges.

In between two charged plates, there can be a neutral zone when the plates have equal and opposite charges. In this case, the electric fields of the positive and negative charges cancel each other out, resulting in a region with no net electric field or potential. When the charges are equal and opposite, the electric field lines within the neutral zone become parallel.

For example, if one plate has a positive charge and the other has an equal negative charge, the positive and negative charges attract each other, resulting in a neutral zone in the middle where the electric field cancels out.
