Electrostatics

The electric field in a region of space is given as \(\mathbf{E}=\left(5 \mathrm{NC}^{-1}\right) x \hat{i}\). Consider point \(A\) on the \(Y\)-axis at \(y=5 \mathrm{~m}\) and point \(B\) on the \(X\)-axis at \(x=2 \mathrm{~m}\). If the potentials at points \(A\) and \(B\) are \(V_A\) and \(V_B\) respectively, then \(\left(V_B-V_A\right)\) is
