Question

The electric flux is negative when the angle between E and A is?
Options
A . cos(theta) is negative when theta > 90 degrees, so the flux is negative - physically, this means the field is entering the surface rather than leaving it.
B 90 degrees
C 45 degrees
D Greater than 90 degrees
Correct Answer
Correct Answer

Option D is the correct answer.

Detailed Explanation

Phi = EA cos(theta). cos(theta) is negative when theta > 90 degrees, so the flux is negative - physically, this means the field is entering the surface rather than leaving it.

Hint

Phi = EA cos(theta).
