일반물리학 1 — Gravitation: Problem 45

Problem 29: Consider an object of mass \( M \) that is small enough to be treated as a particle but large enough that a section of mass \( m \) can be removed and positioned \( 3.0 \text{ mm} \) from the remaining part. To maximize the magnitude of the gravitational force between the removed section and the remaining part, what should the ratio of \( m/M \) be? Problem 45: In Problem 29, what ratio \( m/M \) gives the least gravitational potential energy for the system?
