Why choose a rectangular surface for flux calculation near a wire?

AI Thread Summary
Choosing a rectangular surface for flux calculation near a wire simplifies the mathematical process involved. Rectangular surfaces allow for straightforward integration, making calculations more manageable. In contrast, using irregular shapes would complicate the integral, often requiring numerical techniques. This approach enhances clarity and efficiency in solving electromagnetic problems. Understanding this choice is crucial for mastering flux calculations in physics.

I do not understand conceptually, why we chose the rectangular surface to take the flux over. Can anyone explain this please? i am having great trouble with it.

thank you.

It just makes it easy mathematically to demonstrate the calculation. Any other weird shape will need numerical techniques to do the integral.
 

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...
