If the gravitational field in the space is given as $\displaystyle \left(-\frac{\mathrm{K}}{\mathrm{r}^2}\right)$. Taking the reference point to be at $\displaystyle \mathrm{r}=2 \mathrm{~cm}$ with gravitational potential $\displaystyle \mathrm{V}=10 \mathrm{~J} / \mathrm{kg}$. Find the gravitational potential at $\displaystyle \mathrm{r}=3 \mathrm{~cm}$ in SI unit (Given, that $\displaystyle \mathrm{K}=6 \mathrm{Jcm} / \mathrm{kg}$ )
