Assume that an electric field $\displaystyle \overrightarrow{\mathrm{E}}=30 x^2 \hat{i}$ exists in space. Then the potential difference $\displaystyle \mathrm{V}_{\mathrm{A}}-\mathrm{V}_{\mathrm{O}}$, where $\displaystyle \mathrm{V}_{\mathrm{O}}$ is the potential at the origin and $\displaystyle \mathrm{V}_{\mathrm{A}}$ the potential at $\displaystyle x=2 \mathrm{~m}$ is :
