If you replaced an electron with a proton would the magnitude of the electric and gravitational forces increase, decrease or stay the same?

Would the direction or each of the forces reverse or remain the same?

Thanks

I will be happy to critique your analysis.

If you replace an electron with a proton, the magnitude of the electric and gravitational forces would remain the same. This is because the magnitudes of these forces depend only on the charges and masses involved, but not on whether they are electrons or protons.

The direction of the electric force would reverse, as the electron carries a negative charge (-e) while the proton carries a positive charge (+e). Since opposite charges attract each other, the direction of the electric force would be towards the new proton.

On the other hand, the direction of the gravitational force would not change, as both the electron and the proton have positive masses. Gravity is always an attractive force between any two masses, regardless of their charges. Therefore, the direction of the gravitational force would still be towards the center of mass, which is independent of the particles' charges.

In summary:
1. The magnitude of both the electric and gravitational forces would stay the same.
2. The direction of the electric force would reverse.
3. The direction of the gravitational force would remain the same.
