Since the spacecraft is two earth radii the surface ar of the earth, it is three earth radii over the center.

Given: Radius the the earth re = 6.38 x 10⁶ m r = 1.91 x 10⁷ m massive of the spacecraft multiple sclerosis = 1600 Kg mass of the earth Me = 5.98 x 10²⁴ Kg G = 6.67 X 10⁻¹¹ N.m²/Kg²Formula: F = GMeMs/r² F = (6.67 X 10⁻¹¹ N.m²/Kg²)(5.98 x 10²⁴ Kg)(1,600 Kg)/(1.91 x 10⁷ m)² F = 6.38 X 10¹⁷ N/3.65 X 10¹⁴ m² F = 1,748.5 N
