APFIVE Surface Charge on a Grounded Plate
A neutral conducting plate is oriented perpendicular to a uniform electric field E₀. The plate is then briefly grounded and subsequently isolated. Which of the following describes the resulting surface charge density σ on the faces of the plate?
A
σ = -ε₀E₀ on one side, σ = +ε₀E₀ on the other side
B
σ = -ε₀E₀ on both sides
C
σ = 0 on both sides
D
σ = +ε₀E₀ on both sides
