Electricity (Potential difference between points in circuit)

AI Thread Summary
The discussion centers on finding the potential difference VPQ in a given circuit. Participants suggest using Kirchhoff's laws to analyze the circuit, emphasizing the need to show work for clarity. Attempts to find an equivalent battery and resistance have been unsuccessful. Clear documentation of the calculations, either through photos or typed equations, is encouraged for better assistance. The focus remains on applying Kirchhoff's principles to solve for the potential difference effectively.

You need to show what you've tried so we can see where you went wrong.
You can take photos of your working and post them here using the 'UPLOAD' button (ensure that they are clear and easy to read) or you can simply type out your equations here.
 
There will be counter-clockwise current around the right-hand "loop", and clockwise current around the left-hand "loop". Use these in Kirchoff.
 
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 .
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...
