AI Thread Summary
To determine the electric field from multiple infinite sheets, first calculate the electric field due to each sheet using the formula E = σ/2ε0, considering the sign of σ. The direction of the electric field lines is towards the sheet for negative charge density and away for positive charge density. After determining the electric field for each sheet, vector addition is necessary to find the resultant electric field in a specific region. This approach allows for accurate calculation of the total electric field by considering both magnitude and direction. Understanding these principles is crucial for solving problems involving multiple charged sheets.

Einf sheet= σ/2ε0

The Attempt at a Solution



I understand that the -σ sheet will have E field lines pointing towards the sheet. But I don't understand how to add the other sheets to find the E field in a specific region.

You'll need to figure out the field for each sheet, and it's direction (i.e. either towards or away from the sheet). Then it's vector addition to get the field within each region.
 

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...

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...
