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?
  1. e/ε0
  2. e/ε0
  3. Zero
  4. 2e/ε0

A
e/ε0
B
Zero
C
e/ε0
D
2e/ε0
Solution
Verified by Toppr

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
