Question

An infinite uniform plane of positive charge lies horizontally, and sits above the ground at a height of 10 m overhead. Which of the following statements best describes the electric field above and below the infinite plane?

A-The electric field runs parallel to the surface of the infinite plane on both sides of it.

B-Above the plane, the electric field points down; but below the plane, it points up.

C-Above the plane, the electric field points up; but below the plane, it points down.

D-The electric field points upward both above and below the plane.

E-The electric field points downward both above and below the plane.

Answer 1

for a positive plane of charge field is always away from the plane.

So, above the plane field is up and below the plane it's downward.

Correct option - C
