Answer:
F = 4.816 × 10 ⁻¹⁰ N
Explanation:
mass of earth M = 5.98 × 10²⁴ m, mass of the spacecraft m = 2000 kg,
distance between the spacecraft and earth's center
r = 6380 × 10³m + 6.38 ×10⁶ m = 4.07 × 10¹³ m
Formula for force of gravity is
F= G M m / r²
F = 6.67 × 10⁻¹¹ Nm² /kg² × 5.98 × 10²⁴kg× 2000 kg / (4.07 × 10¹³ m)²
F = 4.816 × 10 ⁻¹⁰ N
