Question

the charge per unit area of large flat sheet is 17.7 C/m2. calculate the electric field intensity at a point just near the surface of sheet measured from its mid-point​

Answer 1

Explanation:

The electric field due to infinite charge sheet is E=2ϵ0σ

So, the charge per unit area, σ=2ϵ0E=2×(8.85×10−12)×3=5.31×10−11C/m2
