Help with this : the field inside a conductor is zero therefore

AI Thread Summary
The discussion centers on the concept that the electric field inside a conductor is zero, leading to various interpretations of the implications for electric potential. Participants explore whether this means the potential inside the conductor is also zero, if it can be defined, or if it matches the potential at the surface. The consensus leans towards the idea that the potential inside the conductor is uniform and equal to the potential at the surface. Clarification on the relationship between electric field and electric potential is emphasized as crucial for understanding the topic. Overall, the discussion highlights the complexities of defining potential in relation to a zero electric field within conductors.

the field inside a conductor is zero therefore
A. the potential inside the conductor is zero
B. the potential cannot be zero
C. The potential inside the conductor is the same as the potential just outside the conductor (on the surface)
D. the potential inside the conductor cannot be defined if the field is zero
E. none of the above is true


I don't get this question. help with this or give me some idea abt it...

Start by asking yourself what is the definition of the Electric Field in terms of the Electric Potential?
 
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...
