Question

Two point charges $(+e)$ and $(-e)$ are kept inside a large metallic cube without touching its sides. Electric flux emerging out of the cube is?

• A. $e/{\epsilon }_0$
• B. $-e/{\epsilon }_0$
• C. Zero
• D. $2e/{\epsilon }_0$

Answer 1

The correct option is C Zero

The Flux coming out from the faces of the cube due to the charge +e will be the same as the flux going into the cube due to –e, the net flux emerging out of the cube will be zero. The option C is zero
