If the distance between two objects is doubled, then the gravitational forces between them become (1/2)² = 1/4 of the original gravitational forces.
If the magnitude of those forces was 10 Newtons before the move then they're 2.5 Newtons after it.
I changed the wording of the discussion to plural, because the wording in the question is misleading. It shouldn't say "Object A attracts Object B" and then let it go at that. Gravitational forces ALWAYS occur in equal pairs. If Object B feels a pull of 10 Newtons toward Object A, then Object A feels a pull of 10 Newtons toward Object B.
The masses don't even matter. Gravity is always there equally in both directions. Your weight on Earth is equal to the Earth's weight on you !
Since we are ignoring air resistance which is a non-conservative force, the potential energy will be completely converted into kinetic energy, resulting in a final kinetic energy of

.
Answer:
0
Explanation:
Weight = mass x gravity
if gravity = 0 then Weight =0 as well
Equatorial currents are primarily westward. This is because the dominant current in the northern hemisphere has a clockwise direction, while the southern hemisphere has a counterclockwise direction. When these two currents meet at the equator, a common westward current exists.
