AI Thread Summary
Rotational angular values in free body diagrams are discussed, but clarity is lacking due to an unclear image and incomplete questions. The first question is believed to be the focus, but a free body diagram is requested for better understanding. The second part of the second question is noted as missing, contributing to confusion. Overall, the thread emphasizes the need for clearer visuals and complete information to facilitate discussion. Effective communication is essential for addressing complex topics like rotational angular values.

There are two questions in the image, and I am really not sure which you are asking about. The second part of the second question is missing in the image.
Also, the image is hard to read. You need to take a closer shot.

Edit... I think it is the first question. If so, please post a free body diagram.
But then the thread title makes no sense.
 
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...
