Question

express gravitational potational at a point and gravitational potential energy of a body in a gravitational field .Establish a relation between them?

Answer 1

$$\begin{gathered} \mathrm{Gravitational}\mathrm{potential}\mathrm{energy}: \\ \mathrm{U}=-\frac{\mathrm{GMm}}{\mathrm{r}} \\ \mathrm{Gravitational}\mathrm{potential}: \\ \mathrm{V}=-\frac{\mathrm{GM}}{\mathrm{r}} \\ \mathrm{Relation}\mathrm{between}\mathrm{Gravitational}\mathrm{potential}\mathrm{energy}\mathrm{and}\mathrm{Gravitationai}\mathrm{potential}: \\ \mathrm{U}=\mathrm{mV} \end{gathered}$$
