Electrostatics 3 Question 15
15. A cubical region of side
(2012)
(a) The net electric flux crossing the plane
(b) The net electric flux crossing the plane
(c) The net electric flux crossing the entire region is
(d) The net electric flux crossing the plane
Show Answer
Answer:
Correct Answer: 15. (a,c)
Solution:
- Option (a) is correct due to symmetry.
Option (b) is wrong again due to symmetry.
Option (c) is correct because as per Gauss’s theorem, net electric flux passing through any closed surface
Here,
Option (d) is wrong because there is no symmetry in two given planes.
