1. The problem statement, all variables and given/known data the helium atom contains two protons in its nucleus. when helium is singly ionized, one of its two electrons is completely removed. the remaining electron orbits the nucleus at a radius of 2.65*10^-11 a) what is the electric field strength created at the location of the electron by the nucleus? b)what is the electrostatic force acting on the electron? 2. Relevant equations 3. The attempt at a solution Just wondering , the question said the helium atom contains two protons, the charge of one proton is +1.60*10^-19, for a) do i multiply by 2? or the value 1.60*10^-19C stay the same?
