The distance between the Earth and the Moon is 3.8 * 10 km, their masses are 6 kg and 7.2 kg, respectively.

The distance between the Earth and the Moon is 3.8 * 10 km, their masses are 6 kg and 7.2 kg, respectively. What is the force of gravity between the Earth and the Moon?

The force of gravity, it is the force of gravitational attraction, is calculated by the formula:
F = (G * m1 * m2) / r ^ 2
Although, according to the condition of the problem, the masses of the Earth and the Moon and the distance between them are extremely small, we will make a calculation using the given data:
G = 6.67 * 10 ^ -11 Nm2 / kg2 – gravitational constant
m1 = 6 kg
m2 = 7.2 kg
r = 3.8 * 10 km = 3.8 * 10 ^ 4 m
F = (6.67 * 10 ^ -11 * 6 * 7.2) / 3.8 * 10 ^ 4 = 75.82 * (10 ^ -11 / 10 ^ 4) = 75.82 * (10 ^ – 15) H
