STANDARD Physics Capacitance MCQ Question
A parallel plate capacitor has two square plates with equal and opposite charges. The surface charge densities on the plates are +σ and −σ respectively. In the region between the plates the magnitude of the electric field is
σ/2ε₀
σ/ε₀
0
none of these.
Correct Answer
Detailed Explanation
The electric field between the plates of a parallel plate capacitor is given by E = σ/ε₀. This is derived from Gauss's law considering the uniform charge distribution on the plates.
