By "see" I meant that I had checked my answer on the internet to see if I was correct in thinking that multipying the charge of an electron, charge of a proton, and k would yield the electrical force between an electron and proton. My answer was 23.10 x 10^-9 which seemed quite different than other answers I saw posted. Either my math was wrong or the numbers I have been using are wrong. I used -1.602 x 10^-19, 1.602 x 10^-19, and the k constant 9 x 10^9. Thanks!

Ok. If you used your calc to get 23E-9 from

9E9*1.6E-19*1.6E-19/(1E-10)^2

then you are right.

I don't know where you got the distance apart from, that of course can change the answer.

To calculate the electrical force between an electron and a proton, you can use the formula for the electrostatic force:

F = (q1 * q2) / r^2

Where:
- F is the electrical force between the charges q1 and q2,
- r is the distance between the charges,
- q1 is the charge of the first object,
- q2 is the charge of the second object.

In this case, you have the charge of an electron (q1 = -1.602 x 10^(-19) C) and the charge of a proton (q2 = 1.602 x 10^(-19) C). The constant k is the Coulomb constant, which has a value of 9 x 10^9 N.m^2/C^2.

By substituting the values into the formula, you can calculate the electrical force between the electron and proton:

F = [(q1 * q2) / r^2]
= [(-1.602 x 10^(-19) C) * (1.602 x 10^(-19) C)] / r^2

However, you provided the value F = 23.10 x 10^(-9), which is different from what you found online.

To ensure you get the correct answer, let's go through the calculation step by step.

Firstly, calculate the product of the charges:

(-1.602 x 10^(-19) C) * (1.602 x 10^(-19) C) = 2.566404 x 10^(-38) C^2

Next, substitute this value, along with the value of the Coulomb constant, into the formula:

F = (2.566404 x 10^(-38) C^2) / r^2

Now, if you have the value of r (the distance between the electron and proton), you can plug it into the formula to get the final result. But since you didn't provide the value of r, I cannot calculate the exact force for you.

Please double-check your calculation and make sure you have the correct value for r. Also, verify the numbers you found online to see if they match the ones you used.
