The figure shows some of the electric field lines corresponding to an electric field. The figure suggests
${E_A} > {E_B} > {E_C}$
${E_A} = {E_B} = {E_C}$
${E_A} = {E_C} > {E_B}$
${E_A} = {E_C} < {E_B}$
How does the electric field lines depend on area ?
What is the flux through a cube of side $a$ if a point charge of $q$ is at one of its comer?
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
The spatial distribution of the electric field due to charges $(A, B)$ is shown in figure. Which one of the following statements is correct
Assertion : Electric lines of force never cross each other.
Reason : Electric field at a point superimpose to give one resultant electric field.
