AI Thread Summary
The discussion focuses on a homework problem related to charge distribution in electrostatic systems. The original poster attempted to solve the problem using energy conservation principles but arrived at an incorrect answer. They reference a similar problem from Irodov's "Basic Laws of Electromagnetism," which suggests that this method is inadequate for the current problem. The poster seeks clarification on how to determine the final charge distribution in the system. Understanding the correct approach to charge distribution is crucial for solving electrostatic problems effectively.

The Attempt at a Solution

I tried to solve the problem using Energy conservation ie., Change in PE = Work done. But that seem to yield wrong answer (1) while the correct answer is 2.

I had read a similar sum in Irodov's ' Basic Laws of Electromagnetism ' in which it was written that this method fails in above case. Please help me solving this.

did you make the final charge distribution in the system?

What does that mean? Or How do I do it?
 

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 'Calculation of Tensile Forces in Piston-Type Water-Lifting Devices at Elevated Locations'

Figure 1 Overall Structure Diagram Figure 2: Top view of the piston when it is cylindrical A circular opening is created at a height of 5 meters above the water surface. Inside this opening is a sleeve-type piston with a cross-sectional area of 1 square meter. The piston is pulled to the right at a constant speed. The pulling force is（Figure 2）： F = ρshg = 1000 × 1 × 5 × 10 = 50,000 N. Figure 3: Modifying the structure to incorporate a fixed internal piston When I modify the piston...

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...
