Compare the magnitudes of the gravitational and electric forces exerted by the nucleus of a hydrogen atom-a single proton \(\left(m_{\mathrm{p}}=1.7 \times 10^{-27} \mathrm{~kg}\right)\) - on an electron \(\left(m_{\mathrm{c}}=9.1 \times 10^{-31} \mathrm{~kg}\right)\) when the two are \(0.50 \times 10^{-10} \mathrm{~m}\) apart.
