    Gauss's law Law
AI Thread Summary
The discussion centers on applying Gauss's Law to find the electric field E(P) and electric potential φ(P) at a point P, given certain parameters R and Q. The original poster expresses confusion about the problem and initially misidentifies variables. Clarification is requested regarding the configuration of charges and the specific location of point P, as these details are crucial for solving the problem. The conversation emphasizes the need for precise definitions and context to effectively use Gauss's Law in this scenario. Understanding the charge distribution and geometry is essential for determining the electric potential at point P.

Welcome to PF!
Could you be more specific? What is R for instance? What is P? What are you looking for?

sorry for this R! mistake.

now i am looking only for the electric potential (sigma) at the point P!

I don't see any point P on the picture. What is the configuration of charges?
 

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...
