Homework Statement



Compare the magnitude of the Coulombic fundamental force to the Gravitational fundamental force. Explain similarities/differences between the 2 types of forces. You have 2 protons separated by 1*10^-4 meters. Calculate the gravitational force of attraction between the two. Calculate the electrostatic force of repulsion between the two. Comment on the relative magnitudes of each force.

Homework Equations



F=kq1*q2/d^2
mg=Gm1m2/d^2

The Attempt at a Solution



uh... i know i have 2 protons. but how can i find q or m?

Um, check the back of your textbook or do a web search? The unit charge is a fundamental constant. The mass of the proton is well known.
