Electrostatics Question 743

Question: For a given surface the Gauss’s law is stated as $ \int _{\vec{E}.dA=0.} $ From this we can conclude that

Options:

A) E is necessarily zero on the surface

B) E is perpendicular to the surface at every point

C) the total flux through the surface is zero

D) the flux is only going out of the surface

Show Answer

Answer:

Correct Answer: C

Solution:

[c] $ \int _{\vec{E}d\vec{A}}=0, $

represents charge inside close surface is zero. Electric field as any point on the surface may be zero.
