What is the graavitaional force between a mass of 120kg and 100kg that are 3 meters apart?

Answer 1

The gravitational force between two masses is

F = G M1 M2/R2

'F' = the force

'G' = the universal gravitational constant

'M1' = the mass of one mass

'M2' = the mass of the other mass

'R' = the distance between the centers of mass of the two masses

In SI units, G = 6.672 x 10-11 Newton-meter2 per kilogram2

F = (6.672 x 10-11) x (120) x (100) / 9 = 8.896 x 10-8 Newton

That's about 0.000 000 32 ounce of force.

Answer 2

Using Newton's law of universal gravitation (F = G * (m1 * m2) / r^2), where G is the gravitational constant (6.67 x 10^-11 N m^2 / kg^2), m1 = 120kg, m2 = 100kg, and r = 3m, we can calculate the gravitational force to be approximately 3.56 x 10^-7 N.
