Answer:
A
Step-by-step explanation:
Force of gravity can be expressed as:
F = GMM/R^2
Where
F = gravitational force
M = mass
R = distance
Also, W = mg
From the above equation, we can deduce that force of gravity actually depends on mass and not volume.
The correct answer is therefore A.
Had twice as much mass
Therefore, the force of gravity pulls down on your school with a total force of 400,000 newtons. The force of gravity pulling down on your school would be exactly twice as much if your school Had twice as much mass
