Question

$F_{g}$ and $F_{e}$ represent gravitational and electrostatic forces respectively between two electrons situated at a distance of 10 cm . the ratio $\mathrm{F}_{\mathrm{g}} / \mathrm{F}_{\mathrm{e}}$ is of the order of\

$F_{g}=\frac{G m_{1} m_{2}}{d^{2}}$\ $=\frac{6.6 	imes 10^{-11} 	imes 9.1 	imes 10^{-31} 	imes 9.1 	imes 10^{-31}}{\mathrm{~d}^{2}}$\ $\mathrm{F}_{\mathrm{e}}=\frac{1}{4 \pi \varepsilon_{0}} \frac{\mathrm{q}_{1} \mathrm{q}_{2}}{\mathrm{~d}^{2}}$\ $=\frac{9 	imes 10^{9} 	imes 1.6 	imes 10^{-19} 	imes 1.6 	imes 19^{-19}}{\mathrm{~d}^{2}}$\ $\frac{\mathrm{F}_{\mathrm{g}}}{\mathrm{F}_{\mathrm{e}}}=$\
