Eight dipoles of charges of magnitude $e$ are placed inside a cube. The total electric flux coming out of the cube will be
The $S.I.$ unit of electric flux is
Total electric flux coming out of a unit positive charge put in air is
The given figure gives electric lines of force due to two charges $q_1$ and $q_2$. What are the signs of the two charges?
The electric field in a region is given $\vec E = a\hat i + b\hat j$ . Here $a$ and $b$ are constants. Find the net flux passing through a square area of side $l$ parallel to $y-z$ plane
