Question

Calculate The Gravitational Force On A Object of 40kg at the surface of earth if radius of earth is R=6400km mass of Earth=6×10(Power Is 24)

Answer 1

The mass of the Earth may be determined using Newton's law of gravitation. ... We know that the acceleration due to gravity is equal to 9.8 m/s2, the Gravitational constant (G) is 6.673 × 10−11 Nm2/kg2, the radius of the Earth is 6.37 × 106 m, and mass cancels out.
