Physics - Gravitation Question with Solution | TestHub

The minimum colatitude on earth upto which the satellite can be used for communication is ${\sin }^{-1}\left(\frac{\mathrm{R}}{\mathrm{R}+\mathrm{h}}\right)$.

The maximum latitudes on earth upto which the satellite can be used for communication is ${\cos }^{-1}\left(\frac{\mathrm{R}}{\mathrm{R}+\mathrm{h}}\right)$.

The area on earth escaped from this satellite is given as $2\pi {\mathrm{R}}^2(1+\sin \theta )$.

The area on earth escaped from this satellite is given as $2\pi {\mathrm{R}}^2(1+\cos \theta )$.
