Find the ratio of the electric and gravitational forces between two protons.

Explanation

`F_"el"=k(q_1q_2)/r^2`
`F_g=G(m_1m_2)/r^2`
`F_"el"=9xx10^9xx((1.6xx10^(-19))xx(1.6xx10^(-19)))/r^2`
`F_g=6.67xx10^(-11)xx((1.67xx10^(-27))xx(1.67xx10^(-27)))/r^2`
`F_"el"/F_g=((9xx10^9)xx(1.6xx10^(-19))xx(1.6xx10^(-19)))/(6.67xx10^(-11)xx(1.67xx10^(-27))xx(1.67xx10^(-27)))`
`=1.24xx10^36`
