How Do You Calculate Resistance in a Radial Cylinder System?

AI Thread Summary
To calculate the resistance in a radial cylinder system, the formula used is Resistance (ohms) = (Ln(R2) - Ln(R1)) * ρ / (π * L). The user seeks confirmation on their solution for the resistance of a current flowing from the inner cylinder to the outer cylinder. The discussion includes an uploaded solution for review. The correct application of this formula is crucial for accurate resistance calculations in cylindrical geometries. The conversation emphasizes the importance of verifying calculations in physics problems.

Homework Statement



Hey guys.
So I got this cylinder with radius R1, R2 and length L as you can see in the pic.
I need to find the resistance of the system for a current that goes from the inner cylinder to the outer cylinder (radial style :smile:).

I uploaded my solution but I'm not so sure about it, can you please tell me if what I did is right?

Thanks in advance.

Hi, Not sure if you sorted this or not, but the correct solution I believe is:-

Resistance (ohms) = (Ln(R2)-Ln(R1)).ρ/(Pi.L)
 

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 'Rolling without slipping on a curved surface'

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .
