# Determine the force of gravitational interaction of two bodies with masses 2m and 8m, located

Determine the force of gravitational interaction of two bodies with masses 2m and 8m, located at a distance of 4m from each other.

Given:

m1 = 2 tons = 2 * 10 ^ 3 kilograms – the mass of the first body;

m2 = 8 tons = 8 * 10 ^ 3 kilograms – the mass of the second body;

R = 4 meters – distance between bodies;

G = 6.67 * 10 ^ -11 m ^ 3 / (c ^ 2 * kg) – gravitational constant.

It is required to determine F (Newton) – the force of gravitational interaction between bodies.

To determine the strength of the gravitational interaction, you need to use the following formula:

F = G * m1 * m2 / R ^ 2 = 6.67 * 10 ^ -11 * 2 * 10 ^ 3 * 8 * 10 ^ 3/4 ^ 2 =

= 106.72 * 10 ^ -5 / 16 = 6.67 * 10 ^ -5 Newton.

Answer: the force of interaction is 6.67 * 10 ^ -5 Newton.
