Newton's law of gravitation states that two masses will

a. not have any affect on each other.
b. attract each other.
c. always fall.

The correct option is B

Explanation:

Newton's law of gravitation states that every particle of an object/matter attract every other particle of another object/matter in the universe with a force directly proportional to the product of the particle masses but inversely proportional to the square the of the distance between them.        

The formula for this law is

F = G × Mm/r²

Where F = Force (in newtons)

M and m = the two masses (in kg)

r = distance
