Calculate the force of gravity (F) between two objects whose masses are m₁ = 100 kg and m₂ = 1000 kg if they are separared by a distance of d = 500 m.

• 2.67 * 10^-11 N

• 0.4 N

• 6.67 * 10^-11 N

• 1.3 * 10^-8 N

At what point is the force of gravity on an object greatest

• At the center of the earth (Core of the earth)

• At twice the distance from the surface of the earth

• At the surface of the earth

• The force of gravity ios the same irrespective of distance from the center of the earth
