Read the following text and answer the following questions on the basis of the same:
Faraday Cage: A Faraday cage or Faraday shield is an enclosure made of conducting material. The fields within a conductor cancel out with any external fields, so the electric field within the enclosure is zero. These Faraday cages act as big hollow conductors you can put things in to shield them from electrical fields. Any electrical shocks the cage receives, pass harmlessly around the outside of the cage.
A point charge of 2 C is placed at centre of Faraday cage in the shape of cube with surface of 9 cm edge. The number of electric field lines passing through the cube normally will be :
  • a)
    1.9 × 105 Nm2/C entering the surface.
  • b)
    1.9 × 105 Nm2/C leaving the surface.
  • c)
    2.0 × 105 Nm2/C leaving the surface.
  • d)
    2.0 × 105 Nm2/C entering the surface.
Correct answer is option 'D'. Can you explain this answer?

The number of electric field lines passing through the cube normally and leaving the surface = Q/ε0
Q = 2 μC = 2 × 10–6 C
ε0 = 8.85 × 10–12 C2/Nm2
∴ Q/ε0 = 2.2 × 105 C2/Nm2
