The gravitational force $$ F $$ between two masses varies in...

Question Analysis
This problem assesses the application of inverse variation in a real-world context, specifically the gravitational force.

Key Concept Explanation
Inverse variation with the square of the distance means , where is a constant. Given two pairs of values, we can determine and use it to find the unknown value.

Step-by-step Solution
1. Identify the constant : Since N when m, we have , so
