MCQ
In the figure shown here, A is a conducting sphere and $B$ is a closed spherical surface. If a-q change is placed at $C$ near $A$, then the electric flux through the closed surface is -
  • A
    Zero
  • B
    Positive
  • Negative
  • D
    None of the above can be predicted

Answer

Correct option: C.
Negative

As the electric field inside the spherical conductor has to be zero the equal and opposite charges will be distributed on the conductor surface such that the induced electric field counters the electric field due to negative charge. For negative charges will be distributed on right and positive on left side
As the spherical region is on right side q inside $< 0.$
