KCET 2025 | Gravitation Question 2 | Physics

The total energy of a satellite in a circular orbit at a distance $(R+h)$ from the centre of the Earth varies as [ $R$ is the radius of the Earth and $h$ is the height of the oribit from Earth's surface]

$-\frac{1}{(\mathrm{R}+\mathrm{h})}$

$\frac{1}{(R+h)^2}$

$-\frac{1}{(R+h)^2}$

$\frac{1}{(\mathrm{R}+\mathrm{h})}$
