With what force is it attracted to the earth with a mass of 49 kg located at an altitude of 400 m from the earth’s surface? R = 6400 km
| December 9, 2020 | education
Decision:
F = (G m M) / (r + h);
r = 6371 + 400 = 6771 km;
F = (6.67 * 10 ^ (- 11) * 40 * 6 * 10 ^ (24)) / (64 * 10 ^ (5) + 4 * 10 ^ (5)) ^ (2) ≈ 346.2 H.
Answer: 346 N.
