일반물리학 1 — Gravitation: Problem 67

Problem 23 (Reference): Two particles are separated by 19 m when their gravitational attraction has a magnitude of \(4.0 \times 10^{-12} \text{ N}\). If the mass of particle 1 is 5.2 kg, what is the mass of particle 2? Problem 67: (a) What is the gravitational potential energy of the two-particle system in Problem 23? If you triple the separation between the particles, how much work is done (b) by the gravitational force between the particles and (c) by you?
