List of top Physics Questions on Newtons law of gravitation asked in AP EAPCET

The acceleration due to gravity at a height $h$ above the Earth's surface is the same as that at a depth $d$ below the surface. If both $h$ and $d$ are much smaller than the radius of Earth $R$, then the relation between $h$ and $d$ is:

The escape velocity of an object from a planet is \(16\,\text{km s}^{-1}\). If the escape velocity of the object from another planet having twice the density and three times the radius of the planet is \(V\sqrt{2}\,\text{m s}^{-1}\), then the value of \(V\) is
