Best Answer: Mass of earth = 5.9742 Ã 10^24 kilograms. To Calculate, Force of gravity F = G.m1.m2 / r^2. where m1 and m2 are two masses, and G is gravitational constant and r is distance. let m1 = M (mass of the Earth) So, F = G.M.m2 / rÂ². Now, assume m2 is a mass on the surface of the planet.
The weight of an object is its mass times the acceleration of gravity. The acceleration of gravity at the center of the Earth is zero. A 1 kg mass at the center of the Earâ¦th still has a mass of 1 kg, but the force of attraction between the 1kg mass and all the other mass around it will add up to zero.
