Electric Fields of Concentric Cylinders

AI Thread Summary
The discussion focuses on calculating the electric fields in a system of concentric cylinders, where the inner cylinder has a linear charge density and the outer cylinder has no net charge. It is established that the electric field inside the concentric cylinder is zero due to its lack of net charge. The participant questions whether this implies that there is no electric field outside the inner cylinder and at the exterior surfaces of the concentric cylinder. They also seek clarification on whether the electric fields inside the charged inner cylinder and outside it can be treated as those of any charged cylinder. Overall, the conversation revolves around understanding the implications of charge distribution on electric fields in this cylindrical configuration.

Homework Statement


A cylinder of radius r is surrounded by a concentric cylinder of inner radius Ra and outer radius Rb. The inner cylinder has a charge density lambda (charge per unit length) and the concentric cylinder has no net charge. I have to find the electric fields:
a)inside the inner cylinder
b)between the inner cylinder and the inner radius of the concentric cylinder
c)inside the volume of the concentric cylinder
d)outside the concentric cylinder


Homework Equations





The Attempt at a Solution


ok since the concentric cylinder has a net charge of zero, the electric field inside it is zero
and since it doesn't has a charge of zero, does that mean that there is no field outside the interior and exterior surfaces of the concentric cylinder too?
and then would the electric fields for inside the inner cylinder and outside of it just be the electric fields for any charged cylinder?

thanks for the help

oops, sorry what i wrote in the attempt, i said the concentric cylinder doesn't have a charge of zero, i meant it does!
 

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
