An electron has mass m_e = 9.11 × 10^–31 kg and charge q_e = –1.6 × 10^–19 C. A proton has mass m_p = 1.67 × 10^–27 kg and charge q_p = 1.6 × 10^–19 C. The electron and proton in the Bohr model of the second excited state of the hydrogen atom are separated by r = 4.761 × 10^–10 m. Calculate E_p, the magnitude of the electric field on the electron due to the proton.
