3) A hydrogen atom consists of a single proton and a single electron bound together by the electric force. When in the ground state, they are separated by 52.9pm. How much energy is required to separate these two particles? (Note: It actually takes less than what you calculate in this problem, since the electron has a significant amount of kinetic energy to start with)

Answer #1

Energy required=kq1q2/r

This is the electrostatic potential energy of a system of 2 charges q1 &q2

=9*10^9*1.6*10^-19*1.6*10^-19/52.9pm

=0.4355*10^-17J
