Explanation:
Since, the two protons are at the initial state of point a and point b. Hence, total mechanical energy at point a and point b is as follows.

or,
where,
= kinetic energy of two protons
So, 

Putting the given values into the above formula we will calculate the value of
as follows.

= 
= 
Now, we will calculate the maximum electric field as follows.
F = 
= 
= 
Therefore, we can conclude that the maximum electric force that these protons will exert on each other is
.
Answer:
atoms bond together and forms molecules
Answer: Not 100% sure but I think it’s C.
Hope this helps! ^^
