The electric field intensity ( E ) due to an infinite sheet of charge with surface charge density ( sigma ) is given by the formula:
[
E = frac{sigma}{2epsilon_0}
]
where ( epsilon_0 ) is the permittivity of free space. The field is uniform and points away from the sheet if the charge is positive, or toward the sheet if the charge is negative.
Answer: d
Explanation: E = σ/2ε.(1- cos α), where α = h/(√(h2+a2))
Here, h is the distance of the sheet from point P and a is the radius of the sheet. For
infinite sheet, α = 90. Thus E = σ/2ε.
