Four point charges $q_1,q_2,q_3$ and $q_4$ are as shown in figure. The flux over the shown Gaussian surface depends only on charges $q_1$ and $q_2$.
Reason: Electric field at all points on Gaussian surface depends only on charges $q_1$ and $q_2$.

Q. Assertion :Four point charges $q_1$, $q_2$, $q_3$ and $q_4$ are as shown in figure. The flux over the shown Gaussian surface depends only on charges $q_1$ and $q_2$. Reason: Electric field at all points on Gaussian surface depends only charges $q_1$ and $q_2$.

Q. In the given question, a statement of Assertion $\left(A\right)$ is given, followed by a corresponding statement of Reason $\left(R\right)$ just below of it. Mark the correct answer.
