Homework Help: Electrical & gravitational force:which one is stronger?

  1. Jun 18, 2007 #1
    1. The problem statement, all variables and given/known data

    I know that electrical/electrostatic i.e Coulob force is stronger than gravitational fiorce.But how much?There's too much contradiction within texts.

    2. Relevant equations



    3. The attempt at a solution

    Different figures've been found in texts.Plz. give accurate figure.

    Surely it depends upon the charges and masses of the particles you are considering. Why not decide on a situation, then put some numbers in and find out?

    well....are you talking about the hierarchy problem? mmm... seems a bit advance for intro physics. OK, yes gravitational "force" is the weakest of all 4 fundamental forces (loosely speaking), but as previous poster said, it can also depend on the mass/charge of the objects involved. A direct comparsion can only be done when you are talking about coupling strength and not the force itself.
