The spatial distribution of the electric field due to two charges $(A,\,B)$ is shown in figure. Which one of the following statements is correct ?
$A$ is $+ve$ and $B$ $-ve$ ; $|A| > |B|$
$A$ is $-ve$ and $B$ $+ve$; $|A| = |B|$
Both are $+ve$ but $A > B$
Both are $-ve$ but $A > B$
Figure shows electric field lines due to a charge configuration, from this we conclude that
How does the electric field lines depend on area ?
Which among the curves shown in Figureb cannot possibly represent electrostatic field lines?
The flat base of a hemisphere of radius $a$ with no charge inside it lies in a horizontal plane. A uniform electric field $\vec E$ is applied at an angle $\frac {\pi }{4}$ with the vertical direction. The electric flux through the curved surface of the hemisphere is
If an electric field is given by $10 \hat{i}+3 \hat{j}+4 \hat{k}$, calculate the electric flux through a surface of area $10$ units lying in $y z$ plane ....... units
