What is the magnitude of each charge in Coulombs according to Coulomb's Law?

AI Thread Summary
The discussion revolves around calculating the magnitude of two identical charges repelling each other with a force of 1 N, positioned one meter apart, using Coulomb's Law. The user attempted to apply the formula F = k(q1q2)/r^2 but expressed confusion over their calculations, leading to an incorrect simplification. A suggestion was made to clarify the values substituted into the equation to solve for the charge magnitude. The key takeaway is that the user needs to correctly input the known values into Coulomb's Law to find the charge in Coulombs. Proper application of the formula will yield the correct answer for the magnitude of each charge.

I have a quick question about using Coulomb's Law, and I was hoping someone would be able to help me.
There are two identical charges which are one meter apart that are repelling each other with a force of 1 N each. What is the magnitude (Coulombs) of each charge?

I tried using Coulomb's law for each of the two charges, and just setting up an arbitrary point where Q1 was located at (0,0) and Q2 is located at (1,0), but I believe this is the wrong way to solve the problem, as I simplified the answer to 1=1.
Is there something that I am missing here? I am using F = k(q1q2)/r^2

Thank you.

You would seem to have everything defined in that equation except the magnitude of the charge. Show us the numbers you plugged into that equation, and solve for q=q1=q2.
 
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'
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...
