how the value of g changes with increase of death find the value of g at the centre of earth
Derive the expression for potential energy of an object at a distance of r from the centre of
earth where are is a very large value comparable to radius of earth

g is not truly constant; it varies from location to location. 9.8 m/s^2 is just an average. The true value varies with your latitude and longitude (mainly due to surface variations in Earth's density). ... For example, if you are at an altitude of 2.2x10^7 m (22000 km), the value of g drops to 0.512 m/s!
Gravitational potential energy at large distances is directly proportional to the masses and inversely proportional to the distance between them. The gravitational potential energy increases as rrr increases.
In physics, a gravitational field is a model used to explain the influences that a massive body extends into the space around itself, producing a force on another massive body. Thus, a gravitational field is used to explain gravitational phenomena, and is measured in newtons per kilogram (N/kg).
