Give the formula of gravitational potential at distance $r$ $(r > R_E)$ from the centre of the Earth.

In a certain region of space,the gravitational field is given by $E = -\frac{K}{r}$,where $r$ is the distance from a fixed point and $K$ is a constant. Taking the reference point to be at $r = r_0$ with potential $V = V_0$,the potential at a distance $r$ is:

$A$ mass of $50 \, \text{kg}$ is placed at the centre of a uniform spherical shell of mass $100 \, \text{kg}$ and radius $50 \, \text{m}$. If the gravitational potential at a point $25 \, \text{m}$ from the centre is $V \, \text{J/kg}$,find the value of $V$.

The gravitational potential energy is maximum at

What is the magnitude of potential energy at infinity distance?

In some region,the gravitational field is zero. The gravitational potential in this region
