Answer:
The satellite to which the Earth's gravity exert the greatest force is:
The fourth.
Step-by-step explanation:
The reason behind this is that in the first place there is no correlation between gravity force and length of an object. In the second place, the distance between all o them and the earth is the same. Now in the third place, the mass of the fourth Satelite is bigger than the rest, therefore it is the one that is dragged to the earth's gravity with a stronger pull because with bigger mass bigger gravity force.
