1. Electric Charges and Fields
normal
There is a square gaussian surface placed in $y-z$ plane. Its axis is along $x-$ axis and centre is at origin. Two identical charges, each $Q$, are placed at point $(a, 0, 0)$ and $(-a, 0, 0)$. Each side length of square is $2a$ then electric flux passing through the square is
A
$\frac{Q}{{6{ \,\in _0}}}$
B
$\frac{Q}{{3{\, \in _0}}}$
C
$\frac{Q}{{12{\, \in _0}}}$
D
zero
Solution
The flux passing through the square of $1 \mathrm{m}$ placed in $\mathrm{XY}$ plane inside the electric field is zero because by Gauss theorem we can say here closed circuit not formed.
