# Distance between two protons

• Tony11235
In summary, the conversation discusses the calculation of the electrostatic force between two protons and the distance required for it to equal the force of gravity acting on a proton at Earth's surface. The individual also mentions the charge of a proton being the same as an electron and suggests looking it up.

The question is how far apart must two protons be for the magnitude of the electrostatic force acting on either one of them to be equal to the force acting on a proton at Earth's surface due to gravity?

I calculated the force acting on a proton at the Earth's surface, very small of course, but in order to find the distance between the two protons shouldn't I know the charge of the protons inorder to have one unknown left, the distance?

The charge on the proton is the same magnitude as the charge on an electron. (The proton's charge is positive, of course.) Look it up!

STUPID!

## 1. What is the distance between two protons?

The distance between two protons can vary depending on the environment, but on average it is about 1 femtometer (10^-15 meters).

## 2. How is the distance between two protons measured?

The distance between two protons is typically measured using techniques such as X-ray crystallography or nuclear magnetic resonance (NMR).

## 3. What factors can affect the distance between two protons?

The distance between two protons can be affected by the presence of other particles, electromagnetic forces, and the temperature and pressure of the environment.

## 4. Can the distance between two protons change?

Yes, the distance between two protons can change due to interactions with other particles or changes in the environment. However, it is typically a very small change on the scale of femtometers.

## 5. Why is the distance between two protons important?

The distance between two protons is important in understanding the structure and behavior of atoms and molecules. It also plays a crucial role in determining the strength of chemical bonds between atoms.
