Answer:
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.

Answer:
Muslim forces ultimately expelled the European Christians who invaded the eastern Mediterranean repeatedly in the 12th and 13th centuries—and thwarted their effort to regain control of sacred Holy Land sites such as Jerusalem. Still, most histories of the Crusades offer a largely one-sided view, drawn originally from European medieval chronicles, then filtered through 18th and 19th-century Western scholars.
