The image above represents the gravitational force.

To compute the gravitational force of a field, three parameters are needed and this parameters are mass (m_{1}), mass (m_{2}) and radius between the masses (R).

The formula for calculating the gravitational force:

F = ^{Gm1m2} / _{r²}

Where;

F = Gravitational force

m_{1} = Mass 1

m_{2} = Mass 2

r = Radius between the masses

Let’s solve an example;

Find the gravitational force of a field when the mass 1 is 8 cm, mass 2 is 10 cm and the radius between masses is 14 cm.

This implies that;

m_{1} = Mass 1 = 8 cm

m_{2} = Mass 2 = 10 cm

r = Radius between the masses = 14 cm

F = ^{Gm1m2} / _{r²}

F = ^{(6.67 x 10-11 x 8 x 10)} / _{196}

F = ^{5.336e-9} / _{196}

F = 2.722e-11

Therefore, the **gravitational force** is **2.722e-11 Newton (N).**
