Potential Difference Between Two Points: 100J of Work Done

AI Thread Summary
The work done to move 4 coulombs of charge in an electric field is 100 joules, leading to the calculation of potential difference. Potential difference, measured in volts, is defined as the work done per unit charge. To find the potential difference, divide the work done (100 J) by the charge (4 C), resulting in a potential difference of 25 volts. Additionally, volts can be broken down into fundamental units of joules per coulomb. Understanding these principles is essential for solving related electrical problems.

Potential difference is measured in Volts. What more fundamental units do Volts break into?
 
so how to solve this question?
 

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...
