Coulombic fundamental force to the Gravitational fundamental force

Click For Summary
SUMMARY

The discussion focuses on comparing the Coulombic force and the Gravitational force between two protons separated by 1*10^-4 meters. The Coulombic force is calculated using the formula F=kq1*q2/d^2, while the Gravitational force utilizes mg=Gm1m2/d^2. The participants conclude that the electrostatic force of repulsion between the protons is significantly stronger than the gravitational force of attraction, highlighting the vast difference in magnitudes between these two fundamental forces.

PREREQUISITES
  • Understanding of Coulomb's Law and Gravitational Law
  • Familiarity with fundamental constants such as the charge of a proton and the mass of a proton

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.
 


oh yeah, i know them now. thanks!
