AI Thread Summary
To find the potential difference Vab in parallel circuits, it's essential to remember that the voltage across all parallel elements is the same. The current in each branch must be calculated, which will then allow for determining the potential difference. Once the voltages Va and Vb are established, Vab can be calculated. Additionally, it's noted that the original post was made in the wrong forum, as there are dedicated homework forums for such queries. Properly identifying the right platform for questions can enhance the likelihood of receiving accurate assistance.

I hope that this one will be ok.
 


You've posted this in the wrong forum. There are homework forums for that. You only need to work out the current in each parallel branch, bearing in mind that the voltage across parallel elements are the same. Then with the current, you can find the potential difference and hence Va and Vb. Then with both Va and Vb you can find Vab.
 


thanks mate!
 

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 .

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...
