AI Thread Summary
The discussion centers on the confusion surrounding the electric field equation E = 7.35i - 5.63(y2 + 9.74)j and its implications in solving the Gaussian Cube question. Participants express difficulty in grasping the notation and concept of the electric field represented by the equation. There is a specific inquiry about calculating the net flux, indicating a need for clarification on this aspect of the problem. Understanding vector notation is acknowledged, but the focus remains on the calculation of net flux. The conversation highlights the challenges faced in applying theoretical concepts to practical problems in physics.

Okay I totally don't understand this problem at all. There is an example in the book also, but I just don't understand how to do it. Like the whole concept of how the E is written. I don't understand what this means: E = 7.35i - 5.63(y2 + 9.74)j.

I figured out the concept behind the vector notation of the eletric field. But now the only thing I don't understand is what is the net flux. How do I calculate the next flux.
 
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...
