Calculate the force of mutual attraction between two bodies whose masses are 2700kg and 3600kg

Calculate the force of mutual attraction between two bodies whose masses are 2700kg and 3600kg, located at a distance of 90m from each other.

Given:

m1 = 2700 kilograms – the mass of the first body;

m2 = 3600 kilograms – the mass of the second body;

R = 90 meters – distance between bodies;

G = 6.67 * 10 ^ -11 N * m ^ 2 / kg ^ 2 – gravitational constant.

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

F = G * m1 * m2 / R ^ 2 = 6.67 * 10 ^ -11 * 3600 * 2700/90 ^ 2 =

= 24012 * 2700 * 10 ^ -11 / 8100 = 6.5 * 10 ^ 7 * 10 ^ -11 / 8100 =

= 6.5 * 10 ^ -4 / 8100 = 0.0008 * 10 ^ -4 = 8 * 10 ^ -8 Newton.

Answer: the force of attraction between bodies is 8 * 10 ^ -8 Newton.
