Center Electrical Electrical field Field Hemisphere

AI Thread Summary

To find the electric field at the center of a hemisphere with a uniform surface charge distribution, the appropriate approach involves using Gauss's law. The electric field direction at the center will point perpendicular to the surface of the hemisphere, directed away from the charge. The magnitude of the electric field can be calculated using the formula E = (σ/2ε₀), where σ is the surface charge density and ε₀ is the permittivity of free space. Understanding these principles is essential for accurately determining the electric field in this scenario. This analysis provides a foundational understanding of electric fields due to charged surfaces.

As a preliminary step, can you determine the direction of the electric field ?

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...

Thread 'Explain this asphalt sheen'

This problem is two parts. The first is to determine what effects are being provided by each of the elements - 1) the window panes; 2) the asphalt surface. My answer to that is The second part of the problem is exactly why you get this affect. And one more spoiler:
