The gravitational force between the objects A. It would increase.
Explanation:
The magnitude of the gravitational force between two objects is given by:
where
G is the gravitational constant
are the masses of the two objects
r is the separation between the objects
In this problem, we are told that one of the object (the one on the right) gains mass: this means that, for instance, the value of increases. We can see from the equation that the gravitational force is directly proportional to the masses: therefore, if one of the masses increases (while the distance between the two objects remains constant), it means that the force also increases.
Therefore, the correct answer is
A. It would increase.

Answer:
481 m
Explanation:
To fall 235 m, the time required is
t = √(2H/g)
t= √(2235/9.8)
t=6.92 seconds.
The supplies will travel forward
6.92 69.4 ≈ 481 m
Therefore, the goods must be dropped 481 m in advance of the recipients.
