The spatial distribution of the electric field due to charges $(A, B)$ is shown in figure. Which one of the following statements is correct
$A$ is $+ve$ and $B\, -ve$ and $|A| > |B|$
$A$ is $-ve$ and $B\, +ve; |A| = |B|$
Both are $+ve$ but $A > B$
Both are $-ve$ but $A > B$
A point charge $q$ is placed at a distance $a/2$ directly above the centre of a square of side $a$. The electric flux through the square is
The wrong statement about electric lines of force is
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
Write $SI$ unit of electric flux.
Gauss’s law is true only if force due to a charge varies as
