Charge Distribution Between Two Conducting Spheres

AI Thread Summary
The discussion focuses on the charge distribution between two conducting spheres of different diameters, connected by a wire and charged with a total of 7.00x10E-6C. The capacitance of each sphere is constant and can be calculated using the formula C = r/ke. The key point is that when the spheres are connected, they become equipotential, meaning their electric potentials equalize. This leads to the conclusion that charge will redistribute until the potential difference is zero. The problem is solved by recognizing that the spheres share the total charge while maintaining equal potential.

[SOLVED] Capacitance and Charge

2 conducting spheres, one of diameter .400m and the other of diameter 1.00m, are separated by a distance large compared to the diameter. The spheres are connected by a wire and the system charged to a total of 7.00x10E-6C (total charge of system). How is the charge distributed between the spheres? (ignore any charge on the wire)

Since the capacitance for each sphere is constant and independent of their charge, I was thinking of using that...just that: C = r/ke for each sphere. Also, C = Q/DV, DV as deltaV. The one thing that I keep getting messed up with is that the electric potential of a sphere changes in respect to charge...so I'm not exactly sure what I can do at that point.

When two conductors are joined by wire, which quantity becomes equal on both of them? (Charge will flow until that thing becomes equal on both.)
 
heh...they become equipotential...solved it, 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'

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...
