We can use the following equation to solve for the gravitational force:

Fg = force due to gravity (N)
G = Gravitational constant
m1,m2 = masses of the objects (kg)
r = distance between the objects (m)
Plug in the given values into the equation:

Answer:
110
Explanation:
to find neutrons we have to subtract the atomic number from the atomic mass.
atomic mass = 183.84
atomic no = 74
183.84 - 74 = 109.84
round off = 110
Ball C has the greatest momentum and ball B has the least amount of momentum.
