  1. A charge Q µC is placed at the centre of a cube, the flux coming out from any surface will be ​​​​​
    1. Q
      		 × 10–6
      6ε0
    2. Q
      		 × 10–3
      6ε0
    3. Q
      24ε0
    4. Q
      8ε0
Correct Option: A

Total flux out of all six faces as per Gauss's theorem should be
Q × 10-6
ε0

Therefore, flux coming out of each face =
Q
 × 10-6 C
6 ε0
