| ASSERTION: A point charge is lying at the center of a cube of each side. The electric flux emanating from each surface of the cube is \[\frac{1}{6}\]th of total flux. |
| REASON: According to Gauss theorem, total electric flux through a closed surface enclosing a charge is equal to \[1/{{\varepsilon }_{0}}\] times the magnitude of the charge enclosed. |
A) If both assertion and reason are true and reason is the correct explanation of assertion.
B) If both assertion and reason are true and reason is not the correct explanation of assertion.
C) If assertion is true but reason is false.
D) If both assertion and reason are false.
E) If assertion is false but reason is true.
Correct Answer: B
Solution :
The electric flux through the cube \[\phi =q/{{\varepsilon }_{0}}\]. A cube has six faces of equal area. Therefore, electric flux through each force \[=\frac{1}{6}\phi =\frac{1}{6}\left( \frac{q}{{{\varepsilon }_{0}}} \right)\].
