derive an expression for Total energy of an Orbit satellite​

Answer 1

$<b> <u> Heya!! </u></b>$

$<b> <i> <u> Total Energy of a Satellite </b> </i> </u>$

★The total energy is obtained by adding the expressions of kinetic and potential energy :-

$<b> → E = P.E + K.E </b>$

= - GMm/(R+h) + ½mv² = -GMm/2 ( R + h )

$<u> But when a Satellite is orbiting close to the surface of earth , r ≈ R </u>$

In this case - total energy is given by :-

$<b> <u> E = -GMm/2R </b> </u>$
