Infinite Planes Eletric Field Question

AI Thread Summary
The discussion centers on understanding electric fields between infinite planes. The original poster seeks clarification on their explanation regarding the electric field configuration. A reference to a specific figure from an external source is provided to illustrate the concept. It is noted that by manipulating the figure, one can replicate the setup of the original problem. The conclusion emphasizes that the electric fields are zero outside the conducting planes and only nonzero between them.

Hi! I have already write everything on the pictures(In attachment), I have already circled the correct answer, however, I am not sure explain it correctly. So, can you check my explanation or question?
Thanks!

This may not help, but see figure 9 of the following,

http://phy214uhart.wikispaces.com/Gauss'+Law

If you take the configuration of figure 9 and copy it, paste it, flip it and connect the two copies together you get the same set up as your problem, the fields will be the same as your problem, fields zero outside and only nonzero between conducting planes.
 
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...
