Gravity's Pull: How Far is the Proton Above the Electron?

In summary, the conversation discusses the concept of an electron being held up against the force of gravity by the attraction of a fixed proton located some distance above it. The conversation suggests using relevant equations and making a sketch of the situation to determine the two forces acting on the electron and their difference.

Hello @Johann0101 ,
:welcome: !​

PF is here to help you with your exercises, not to do them for you. See guidelines.
So we want you to list the relevant equations and post an attempt at solution.
What equations do you have available in your toolkit that could help you here ?

What also helps: make a sketch of the situation and draw a few forces :smile:

Focus your attention at the electron. Which are the two forces that act upon it? (neglecting the gravitational force between the proton and the electron which would give a 3rd force.) What should be the difference of these two forces since the electron is held fixed in its position?
 

FAQ: Gravity's Pull: How Far is the Proton Above the Electron?

What is "Gravity's Pull"?

"Gravity's Pull" refers to the force of gravity between two objects. In this context, it specifically refers to the gravitational attraction between a proton and an electron.

How far is the proton above the electron?

The distance between a proton and an electron can vary, but on average, the proton is about 10,000 times closer to the electron than the electron is to the nucleus of an atom.

How does gravity affect the proton and electron?

Gravity is a very weak force compared to the other fundamental forces in the universe, such as electromagnetism. Therefore, the gravitational pull between a proton and an electron is relatively small and does not significantly affect their behavior within an atom.

Why is the proton closer to the electron than the electron is to the nucleus?

This is due to the fact that the proton has a positive charge and the electron has a negative charge. Opposite charges attract each other, so the electron is pulled towards the positively charged proton.

Can gravity be used to explain the behavior of subatomic particles?

While gravity does play a role in the behavior of subatomic particles, it is not the primary force at this scale. The other fundamental forces, such as electromagnetism and the strong and weak nuclear forces, have a much greater influence on the behavior of subatomic particles.
