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 $A > B$
If the electric field intensity in a fair weather atmosphere is $100 \,V / m$, then the total charge on the earth's surface is ............ $C$ (radius of the earth is $6400\,km$ )
How much electric flux will come out through a surface $S = 10\hat j$ kept in an electrostatic field $\vec E = 2\hat i + 4\hat j + 7\hat k$.........$units$
Write Gauss’s law and give its expression.
A cylinder of radius $R$ and length $L$ is placed in a uniform electric field $E$ parallel to the cylinder axis. The total flux for the surface of the cylinder is given by-
In figure $+Q$ charge is located at one of the edge of the cube, then electric flux through cube due to $+Q$ charge is
