Physics - Electrostatics Question with Solution | TestHub

Figure shows three points $\mathrm{A},\mathrm{B}$ and $\mathrm{C}$ in a region of uniform electric field $\vec{E}$. The line $AB$ is perpendicular and $\mathrm{BC}$ is parallel to the field lines. Then which of the following holds good?
Where ${\mathrm{V}}_{\mathrm{A}},{\mathrm{V}}_{\mathrm{B}}$ and ${\mathrm{V}}_{\mathrm{C}}$ represent the electric potentials at the points $\mathrm{A},\mathrm{B}$ and $\mathrm{C}$ respectively.
