Question

A weird shaped conductor is given an excess charge of -40 C. A closed surface is chosen such that it is perfectly contained well inside the bulk of the conductor. The Electric flux through this surface will be?

• A. $\frac{-40}{{\epsilon }_o}$
• B. $\frac{40}{{\epsilon }_o}$
• C. zero
• D. Insufficient data

Answer 1

The correct option is C zero

As you probably know that any excess charge given to any conductor resides on its surface such that there is no electric field inside the volume of the conductor.

So clearly, Electric flux = 0; for any gaussion surface wholly contained inside the boundaries of any conductor.
