Electrical & gravitational force:which one is stronger?

AI Thread Summary
The discussion centers on the comparison between electrical (Coulomb) and gravitational forces, with the consensus that the Coulomb force is significantly stronger. However, the strength of these forces can vary based on the specific charges and masses of the particles involved. Participants note that while gravitational force is the weakest of the four fundamental forces, a direct comparison requires considering coupling strength rather than just force magnitude. There is a call for clarity, as conflicting figures in texts contribute to confusion. Ultimately, understanding the context and specific conditions is crucial for accurate comparisons between these forces.

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.

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
