An AC circuit w/ only an inductor

AI Thread Summary
In an AC circuit with only an inductor, the current lags the voltage by 90 degrees. This means that the voltage reaches its peak before the current does. The discussion emphasizes understanding the phase relationship between current and voltage in inductive circuits. Participants are encouraged to share their thoughts and clarify where they are confused. The correct answer to the posed question is that the current lags the voltage by 90 degrees.

Hi,

The answer for your question is here;
The current lags the voltage by 90degree.
 
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...
