The figure shows some of the electric field lines corresponding to an electric field. The figure suggests
${E_A} > {E_B} > {E_C}$
${E_A} = {E_B} = {E_C}$
${E_A} = {E_C} > {E_B}$
${E_A} = {E_C} < {E_B}$
Three positive charges of equal value $q$ are placed at vertices of an equilateral triangle. The resulting lines of force should be sketched as in
An infinite line charge is at the axis of a cylinder of length $1 \,m$ and radius $7 \,cm$. If electric field at any point on the curved surface of cylinder is $250 \,NC ^{-1}$, then net electric flux through the cylinder is ............ $Nm ^2 C ^{-1}$
The spatial distribution of the electric field due to charges $(A, B)$ is shown in figure. Which one of the following statements is correct
An uncharged sphere of metal is placed in between two charged plates as shown. The lines of force look like
A sphere encloses an electric dipole with charge $\pm 3 \times 10^{-6} \;\mathrm{C} .$ What is the total electric flux across the sphere?......${Nm}^{2} / {C}$
