20 N north because He is pushing it 20 newtons north.
Alpha particles, because they are the heaviest ones (helium nuclei) and will travel around the body.
Answer:
Yes, it's correct
Explanation:
Newton's second Law states that the acceleration of an object is proportional to the net force applied on it, according to the equation:

where
F is the net force on the object
m is the mass of the object
a is the acceleration of the object
We can re-arrange the previous equation in order to solve explicitely for a, the acceleration, and we find:

So, we see that the acceleration is proportional to the net force and inversely proportional to the mass of the object.
