Answer 1

The force F1 = 10 N when d1 = 4 m. The square of 4 m is d1² = 16 m². When d = 2 m, its square is d2² = 4 m². Solving for F2

F2× d2² = F1× d1²

F2 × 4m² = 10 N × 16 m²

F2 = (10 N × 16 m^2) / 4 m² F2

= 10 N× (16 m² /4 m²)

F2 = 10 N × 4

F2 = 40 N

The gravitational force produced when they are kept 2 meters apart is 40 N.
