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
.
The centripetal force is the gravitational force of attraction between the Earth and the Moon.
Also, the gravitational force of attraction between the Earth and the Sun is the centripetal force that causes the Earth to stay in orbit around the Sun.
Also, the gravitational force of attraction between a TV satellite, a weather satellite, or a GPS satellite and the Earth is the centripetal force that causes each satellite to stay in orbit around the Earth.
Option B makes best sense, correct me if i’m wrong
Answer:
push on objects force is required. pull force is resli8
