1. Electric Charges and Fields
hard
Five charges $+q,+5 q,-2 q,+3 q$ and $-4 q$ are situated as shown in the figure.
The electric flux due to this configuration through the surface $S$ is
A
$\frac{5 q}{\epsilon_0}$
B
$\frac{4 q}{\epsilon_0}$
C
$\frac{3 q}{\epsilon_0}$
D
$\frac{q}{\epsilon_0}$
(JEE MAIN-2024)
Solution
As per gauss theorem,
$\phi=\frac{q_{\text {in }}}{\epsilon_0}=\frac{q+(-2 q)+5 q}{\epsilon_0}$
$\frac{4 \mathrm{q}}{\epsilon_0}$
