The electric field at a point in a region is given by $\displaystyle \overrightarrow{\mathrm{E}}=\alpha \frac{\overrightarrow{\mathrm{r}}}{|\overrightarrow{\mathrm{r}}|^{3}}$, where $\displaystyle \alpha$ is a constant and r is the distance of the point from the origin. The magnitude of potential of the point is:
