Electrical & gravitational force:which one is stronger?

[shehri]

Homework Statement

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

Homework Equations

Fe=Kq1q2/r2

Ge=Gm1m1/r2

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.
