1. The problem statement, all variables and given/known data
In the Bohr model of a hydrogen atom, what is the magnitude of the electric force exerted between the proton and the electron when the electron is in the n = 1 state?


2. Relevant equations
E= - 13.6 eV/ n^2


3. The attempt at a solution

I simply plugged in the value for n and got an answer of -13.6 eV. I do not understand why this is incorrect. This is an online homework assignment and asks for the answer in N. Is this where I am making my mistake? Or am I using the wrong formula?

You calculated an energy. The problem asks for a force. Force and energy are different.

What equation have you been given that can be used to calculate the force between two charges?

ohh.. so i just use F= kq1q2/r^2

and since it is in the n=1 state, i would use Bohr's radius for r... correct?
