What is the gravitational attraction between Mass A (200kg) and Mass B (500kg) ? 12m distance between the two masses.

Fg = 4.63*10^-8 N

Explanation:

The gravitational attraction between two masses m1 and m2 is given by:

Fg = G*m1*m2 / (r^2), where m1 = 200kg, m2 = 500kg, G is gravitational constant

then:

Fg = [ (6.67408*10-11) (200) (500) ] / (12^2)

= 4.63*10-8 N

therefore, the gravitational attraction between the mass is 4.63*10-8 N.
