As the question before, with the electron replaced by a proton, i thought that the electric and gravitaional forces would increse, with the electron capture mass proportion and that the direction of forces would reverse as they charges reverses, is this along the right line please
Your explanation is mostly correct. When you replace the electron with a proton, both the electric and gravitational forces will indeed increase.
The electric force between two charged particles is given by Coulomb's Law, which states that the force is directly proportional to the product of the charges and inversely proportional to the square of their separation. Since both the proton and the electron have positive charges, reversing the charges means that they will now attract each other instead of repelling. The magnitude of the electric force between them will be the same as before, but now it will be attractive instead of repulsive.
Similarly, the gravitational force between two objects is given by Newton's Law of Universal Gravitation, which states that the force is directly proportional to the product of their masses and inversely proportional to the square of their separation. By replacing the electron with a proton, the mass has increased, which means the gravitational force between them will be greater.
So, overall, you are correct. Replacing the electron with a proton will result in both the electric and gravitational forces increasing, with the direction of the electric force reversing due to the reversed charges.
