Question

When is electric flux through a surface considered positive, according to the document?
Options
A When the electric field is parallel to the surface.
B When the electric field is perpendicular to the surface and pointing out of the surface.
Correct Answer
C When the electric field is perpendicular to the surface and pointing into the surface.
D When the surface encloses a net negative charge.
Correct Answer

Option B is the correct answer.

Detailed Explanation

Page 12 states, 'Flux out of a surface is positive.' This occurs when the electric field is perpendicular to the surface, coming out of it (as shown in Fig. 2.7c).

Hint

Consider the convention for 'out of' versus 'into' a surface.
