In the nucleus density gravitation is greater than electrostatic force

Let's compare the density gravitation and electrostatic force between two protons. Temporarily, gravitational constant is believed to be accurate in the following discussion. Proton mass is about 1.67x10$^{-27}$kg, radius is about r$=$1.0x10$^{-15}$m H$=$6.67x10$^{-11}$k$=$9x10$^{9}$ Proton charge is e$=$1.6x10$^{-19}$coulomb Proton density is p1$=\frac{1.67\times 10^{-27}}{\frac{4}{3}\pi r^{3}}=$ $\frac{1.67X10^{-27}}{4.1762X10^{-45}}=4X10^{17}$kg/m$^{3}$ F$_{\mathrm{d}} \quad =$H$\frac{p_{1}^{2}}{R^{2}}$ F$_{\mathrm{e}}$ $=K\frac{e^{2}}{R^{2}}$ Obviously F $_{\mathrm{d}} \quad_{\mathrm{>>}}$ F $_{\mathrm{e}}$, Tt is apparent that F$_{\mathrm{d}}$ is much greater than F$_{\mathrm{e.}}$.
