(i) Determine the gravitational potential energy of a two-particle system of a 5.3 kg particle and a 2.3 kg particle having a gravitational attraction of magnitude 2.4 x 10-12 N?
(ii) When you triple the separation among the particles, determine how much work is completed by the gravitational force among the particles?
(iii) If you tripled the separation among the particles, determine how much work was completed by you?
