Positive & Negative charge of Tungsten

AI Thread Summary
To determine the positive and negative charge in a 50g Tungsten ring, first calculate the number of atoms using the standard atomic weight of Tungsten, which is 183.84. Each Tungsten atom has 74 protons, contributing a positive charge of +1.6 x 10^-19 C per proton. Additionally, each atom has 74 electrons, each with a negative charge of -1.6 x 10^-19 C. The total charge can be found by multiplying the number of atoms by the charge of protons and electrons, respectively. The discussion emphasizes the need to consider all electrons and protons, not just those in the outer orbital.

ok, so how many atoms are there in the ring?

and how much charge in each atom? :smile:​
 
There are 3 electrons in the outer orbital? and there is -1.6 x 10^-19 C Negative charge in each electron? So do I just multiply those two together?

Does that sound correct?
 
isn't it asking for the charge of all the electrons (ie not just the outer ones)?

(and, separately, all the protons)
 

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'

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...
