Question

The binding energy of the earth moon system can be expressed as ( $\mathrm{M}_{\mathrm{e}}$ Mass of the earth $\mathrm{M}_{\mathrm{m}}$ Mass of the moon $\mathrm{r}_{\mathrm{em}}$ Distance between the earth and moon)\

Professor PC Thomas Classes · Answer

Binding energy of the earth moon system is the energy released when its constituents are brought from infinity to form the system.\ T.E of Earth moon system $=\frac{-\mathrm{GM}_{\mathrm{e}} \mathrm{M}_{\mathrm{m}}}{2\mathrm{R}_{\mathrm{em}}}$\ where $\mathrm{M}_{\mathrm{e}}=$ Mass of earth\ $\mathrm{M}_{\mathrm{m}}=$ Mass of moon\ $\mathrm{R}_{\mathrm{em}}=$ distance between earth and moon\Hence the value of binding energy will be $\frac{G M_{e} M_{m}}{2 r_{e m}}$\
