How Does an Insulating Sphere Affect Electric Field Distribution?

AI Thread Summary
An insulating sphere retains its charge distribution, preventing charges from moving freely like in a conducting sphere. Unlike conductors where the electric field inside is zero, the electric field within an insulating sphere can vary based on the charge distribution. In this scenario, the charge is concentrated on a hemisphere, affecting the resulting electric field differently than if it were uniformly distributed. Understanding the implications of charge distribution on electric field behavior is crucial in analyzing the effects of insulating materials. The discussion highlights the importance of distinguishing between conductors and insulators in electric field analysis.

The Attempt at a Solution


im not sure why this is an answer. The first part I noticed is that it is an insulating sphere. Insulator means that all the charges can't leave the sphere. What i do know is that in a conducting sphere, charges go to the surface and the field of any distance inside the sphere is 0. Thus, I'm assuming the insulator has some effect on this..

The charge distribution is given, and the question is about the field resulting from that charge distribution.

The charge in this hypothetical situation is spread on a hemisphere, so this is a different situation.
 

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...
