The 3rd truck has the greatest force of gravity acting on it.
Explanation:
On the Earth's surface, the force of gravity acting on an object is given by
[tex]F=mg[/tex]
where
m is the mass of the object
g is the acceleration of gravity
From the equation, we observe that the force of gravity is directly proportional to the mass of the object.
In this problem, we have 4 trucks, of which:
- The 1st one has 4 boxes
- The 2nd one has 3 boxes
- The 3rd one has 6 boxes
- The 4th one has 2 boxes
Since the boxes have all the same mass, this means that the mass of the 3rd truck is larger than the others: therefore, the 3rd truck has the greatest force of gravity acting on it.
