Question:

A parallel plate capacitor with plates of area 1m² each, has a plate separation of 0.1m. If the electric field between the plates is 100N/C, the magnitude of charge on each plate is: (Take ε₀=8.85×10⁻¹²C²N⁻¹m⁻²)

7.85×10⁻¹⁰C

6.85×10⁻¹⁰C

9.85×10⁻¹⁰C

8.85×10⁻¹⁰C

Solution:

The correct option is D
8.85×10⁻¹⁰C
E = σ/ε₀ = Q/Aε₀
