Question
Two small objects with masses m and M are originally a distance r-apart and the gravitational force on each has a magnitude F. The second object has its mass changed to 2M and the distance is changed to r/4. What is the magnitude of the new gravitational force? Two small objects with masses m and M are originally a distance r-apart and the gravitational force on each has a magnitude F. The second object has its mass changed to 2M and the distance is changed to r/4. What is the magnitude of the new gravitational force?Explanation / Answer
F = G M m / r^2
now F' = G (2M)(m) / (r/4)^2
F' = 32 G M m / r^2
F' = 32 F
Ans: 32F
