The radius of the orbit of a geostationary satellite is (mean radius of the earth is $R$ , angular velocity about an axis in $ω$ and accleration due to gravity on earth's surface is g)

Options:

Answer:

Solution:

$m r ω^{2} r ω^{2} r^{3} r = \frac{GM m}{r ^{2}} = \frac{GM}{r ^{2}} = \frac{GM}{ω ^{2}} = \frac{GM}{R ^{2}} \times \frac{R ^{2}}{ω ^{2}} = g \frac{R ^{2}}{ω ^{2}} = (\frac{R ^{2} g}{ω ^{2}})^{1/3}$
