Calculate the acceleration due to gravity on the surface of a satellite having a mass of 7.4×10 22 kg and a radius of 1.74×10 6 m (G = 6.7×10 -11 Nm 2 /kg 2 ). Which satellite do you think it could be?

Question

Calculate the acceleration due to gravity on the surface of a satellite having a mass of 7.4&#xD7;10 22 kg and a radius of 1.74&#xD7;10 6 m (G = 6.7&#xD7;10 -11 Nm 2 /kg 2 ). Which satellite do you think it could be?

Philoid · Accepted Answer

Acceleration due to gravity, g = G * M/R²

Mass, M = 7.4 * 10²² kg

Radius, R = 1.74 * 10⁶m

Gravitational constant, G = 6.67 * 10^-11 Nm² kg^-2

g = 6.67 * 10^-11 * 7.4 * 10²²/ (1.74 * 10⁶)²

g = = 1.637 m/s²

As the value of g = 1.637 m/s², which is one-sixth the value of g on earth, the satellite could be moon.
