B The electric field is pointing out of the surface.
C The electric field is pointing into the surface.
Correct Answer
D The electric field is uniform across the surface.
Correct Answer

Option C is the correct answer.

Detailed Explanation

The document states, 'Flux into a surface is negative.' This corresponds to the electric field being perpendicular to the surface and going into the surface (page 12, Fig. 2.7d and text below it).

Hint

Refer to the sign convention for flux in relation to the direction of the electric field on page 12.
