Worked Solution & Example Answer:Two parallel metal plates of separation $a$ carry equal and opposite charges - AQA - A-Level Physics - Question 15 - 2017 - Paper 2
Step 1
Which graph best represents how the electric field strength $E$ varies with the distance $x$ in the space between the two plates?
Answer
The electric field between two parallel plates is uniform, meaning it maintains a constant value as you move through the space between the plates. Therefore, the correct representation of this phenomenon would be a horizontal line at a constant value of between the plates and returning to zero outside the plates. Thus, the correct graph is A.
