## Homework Statement

Calculate the ratio of the magnitude of the attractive gravitational force to the repulsive electrostatic force between two protons.

## Homework Equations

Mass of proton = M = m = 1.672e-27 kg

g = 9.80665m/s

^{2}

Q = q = 1.60219e−19 C

k = 8.9875e9 N•m2/C2[tex]F_{Gravity}=g\frac{Mm}{r^{2}}[/tex]

[tex]F_{electric}=k\frac{Qq}{r^{2}}[/tex]

## The Attempt at a Solution

The radius [tex]r[/tex] is not given, so I attempted to find it algebraically by plugging in numbers, and I get:

[tex]F_{gravity}=\frac{2.74m/s^{2}\cdot kg^{2}}{r^{2}}[/tex]

I feel certain I am on the wrong track.
