What the gravitational potential at a distance 7.2x107 m from the centre of the planet if The gravitational potential at a distance 2.26x107 m from the centre of a planet of radius 8.55x106 m is -5.6?

The gravitational potential ( V ) at a distance ( r ) from the center of a planet can be calculated using the formula ( V = -\frac{GM}{r} ), where ( G ) is the gravitational constant and ( M ) is the mass of the planet. Given that the potential at ( 2.26 \times 10^7 ) m is -5.6, we can use this information to determine the mass of the planet. By assuming the mass remains constant, we can then find the gravitational potential at ( 7.2 \times 10^7 ) m, which will be less negative (i.e., closer to zero) than -5.6 because the potential becomes less negative as the distance increases. However, the exact value requires further calculations based on the mass derived from the initial potential.
