Question

The charge per unit area of a large flat sheet of charge is 3mue colunmb per meter square calculate the electric field intensity at a point just near the surface of the sheet, measure from its mid point?

Answer 1

Explanation:

The electric field due to infinite charge sheet is E=

2ϵ

0

σ

So, the charge per unit area, σ=2ϵ

0

E=2×(8.85×10

−12

)×3=5.31×10

−11
