The force of attraction between m1 and m2 is 26 n. what will this force become if m2 is tripled?

In order to determine the effect, we will first consider the mathematical expression of Newton's law of gravitation:
F = (Gm₁m₂)/r², where G is the gravitational constant, m represents the mass of a body, and r is the separation between the two bodies. 
It is visible that the force is directly proportional to the product of the two masses. Therefore, if one mass is kept constant and the other is tripled, the force will also triple. Thus, the force will be:
26 * 3
= 78 Newtons

Ibelieve the answer is b. dugout

One splits the atoms and molecules  the other combines them
