Electrostatics

Assume that an electric field \(\mathrm{E}=30 \mathrm{x}^2 \hat{\mathrm{i}}\) exists in space. If '\(\mathrm{V}_0\)' is the potential at the origin and '\(V_A\)' is the potential at \(x=2 \mathrm{~m}\), then the potential difference \(\left(\mathrm{V}_{\mathrm{A}}-\mathrm{V}_0\right)\) is
