) The centre of a mass, m, is at a distance, r, from the centre of a larger mass M. Assuming there are no other masses present, what is the maximum gravitational potential energy that mass m and mass M can have in this situation? Your value must be explained to gain any marks.

U = - G m M / r

Explanation:

The gravitational potential energy is given by the expression

         U = - G m₁ m₂ / r

dodne G is the gravitational cosntnate (G = 6.67 10⁻¹¹¹), m and m are the mass of the bodies involved

subtype the given values

         U = - G m M / r

a lot of it means it can be "burned" for energy and sold at one price. if it is scarce, the price will go up
