The electron and proton of an atom are separated by \(8.5\times10^{-10}\) m. Find the ratio between the electric force and the gravitational force between the two particles. [Electron charge \(=-1.6\times10^{-19}C\), Electron mass \(=9.11\times10^{-31}\) kg, Proton mass \(1.67\times10^{-27}\) kg, Gravitational Constant \(G=6.67\times10^{-11}Nm^{2}kg^{-2}$]
