Jaka masę Ziemia przyciąga z siłą 1N (niutona)?

F = 1 N Mz = 6 *10²⁴ kg G = 6,67 *10⁻¹¹ N * m²/kg² R = 6370 km = 6370000 m = 6,37 *10⁶ m m = ?   F = G * Mz * m /R² F * R² =  G * Mz * m m = F * R² / G * Mz   m = 1 N * (6,37 *10⁶ m )²/6,67 *10⁻¹¹ N * m²/kg² * 6 *10²⁴ kg m = 40,58 *10¹² N * m²/40,02 *10¹³ N * m²/kg m ≈ 1,013  * 10⁻¹ kg m ≈ 0,1 kg
