Question
(Part1 of 3 )-Find the magntude ofte gravitational force a 65.9 kg person would experience while standing on the surface of Earth with a mass of 5.98 x 10^24 kg and a radius of 6.37 x 10^6 m. The universal gravitational constant is 6.673 x 10^-11 N x m^2/kg^2. Answer in units of N.(Part2 of3)- Find the magnitude of the gravitational force on Mars, with a mass of 6.34 x 10^23 kg and a radius of 3.43 x 10^6 m. Answer in units of N.
(Part 3 of 3 ) - Find the magnitude of the gravitational force on Pluto,with a mass of 1.32 x 10^22 kg and a radius of 1.15 x10^6 m. Answer in units of N.
Explanation / Answer
m1 = 65.9 kg m2 = 5.98 *10^24 kg r = 6.37 *10^6 m G = 6.673 × 10-11 Nm2/kg2 Since F = Gm1m2/r^2 F =(6.673 × 10-11 Nm2/kg2) * 65.9 kg * 5.98 *10^24 kg / (6.37 *10^6 m)^2 F = 648 N
