NEET Physics Electric Potential MCQ Question

Type: MCQ-diagram based-Medium-Class 12

Consider a diagram showing two parallel plates with charge densities σ\sigma and σ-\sigma on plates 1 and 2, respectively, creating an electric field in the region between them. If EE represents the electric field between the plates, which of the following correctly describes the electric field EE in terms of σ\sigma and ε0\varepsilon_0?

Question diagram
A

E=σε0E = \frac{\sigma}{\varepsilon_0}

B

E=2σε0E = \frac{2\sigma}{\varepsilon_0}

C

E=σ2ε0E = \frac{\sigma}{2\varepsilon_0}

D

E=0E = 0

Correct Answer

Option A

Detailed Explanation

The electric field EE between the parallel plates is given by E=σε0E = \frac{\sigma}{\varepsilon_0}, as the fields from both plates add up between them but cancel outside.
