Coulombic fundamental force to the Gravitational fundamental force

AI Thread Summary
The discussion focuses on comparing the Coulombic force and the gravitational force between two protons separated by 1*10^-4 meters. Participants calculate the gravitational force using the equation mg=Gm1m2/d^2 and the electrostatic force using F=kq1*q2/d^2. The conversation highlights that while both forces act at a distance, the Coulombic force is significantly stronger than the gravitational force. Participants confirm the known values for charge and mass of protons to complete their calculations. The thread emphasizes the vast difference in magnitudes between these two fundamental forces.

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

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!
 

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'A cylinder connected to a hanging mass'

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
