For a satellite under motion-P-E-x2212-GMmrK-E-GMm2rT-E-x2212-GMm2rThe energy required to remove an Earth-apos-s satellite-xA0-of mass m from its orbit of radius r to infinity is called as Binding Energy-As B-E-x2212-T-E-x2234-B-E-GMm2r

The energy required to remove an Earth's satellite of mass m from its orbit of radius r to infinity isGMmr−GMm2rMm2rGMm2r

For a satellite under motion:P.E.=−GMmrK.E.=GMm2rT.E.=−GMm2rThe energy required to remove an Earth's satellite of mass m from its orbit of radius r to infinity is called as Binding Energy.As B.E.=−T.E∴B.E.=+GMm2r

The energy required to remove an Earth's satellite of mass $m$ from its orbit of radius $r$ to infinity is
$\frac{G M m}{r}$
$\frac{- G M m}{2 r}$
$\frac{M m}{2 r}$
$\frac{G M m}{2 r}$
