Physics - Electrostatics Question with Solution | TestHub

The electric field strength depends only on the $x,y$ and $z$ coordinates according to the law $E=\frac{\mathrm{a}(x\hat{\mathrm{i}}+\mathrm{y}\hat{\mathrm{j}}+\mathrm{z}\hat{\mathrm{k}})}{{\left({\mathrm{x}}^2+{\mathrm{y}}^2+{\mathrm{z}}^2\right)}^{3/2}}$, where $\mathrm{a}=122.5\mathrm{SI}$ unit and is a constant. Find the potential difference (in volt) between ( $3,2,6$ ) and ( $0,3,4$ ).
