    K = - ½U

    Explanation:

    From Newton's law of gravitation, the formula for gravitational potential energy is;

    U = - GMm/R

    Where,

    G is gravitational constant

    M and m are the two masses exerting the forces

    R is the distance between the two objects

    Now, in the question, we are given that kinetic energy is;

    K = GMm/2R

    Re-rranging, we have;

    K = ½ (GMm/R)

    Comparing the equation of kinetic energy to that of potential energy, we can derive that gravitational kinetic energy can be expressed in terms of potential energy as;

    K = - ½U
