Problem

Two protons are

1.0\,\text{fm}

apart. Using

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

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

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

and

m_p=1.67\times10^{-27}\,\text{kg}

, find the ratio of the magnitude of the electrostatic repulsive force to the gravitational attractive force between them.
