Calculate the ratio of the magnitude of the electrostatic force to the gravitational force between two electrons separated by

1.0\,\text{nm}

. Use

e = 1.6\times10^{-19}\,\text{C}

m_e = 9.1\times10^{-31}\,\text{kg}

k = 9.0\times10^{9}\,\text{N\,m}^2\,\text{C}^{-2}

and

G = 6.67\times10^{-11}\,\text{N\,m}^2\,\text{kg}^{-2}
