The train would need the greatest amount of force due to weight! If you think of it, a baseball won't need much force to stop it, but if you have a heavy train, it will need excessive force to stop the train. The answer would be #3
I hope this answer helps!
Sorry if it doesn't make sense, as I don't know that much about physics! I am just thinking of what makes sense.
Answer:
The answer to your question is below.
Explanation:
Atoms are composed by three different subparticles
- protons are small particles positive charged located in the nucleus.
- neutrons are small particles without a charged located in the nucleus.
- electrons are the smallest subparticles and are negatively charged.
In a neutral atom, the amount of positive charges (protons) is equal to the amount of negative charges (electrons) so it does not have any charge.
If a neutral atom gains one or more electrons it would be negative.

A Bowling ball and a napkin would fall with the same acceleration in space where there is vacuum. Basically where there is no drag force and the two objects are freely falling under gravity. The two objects would fall with same acceleration due to gravity.
