AI Thread Summary
To solve four equations with four unknowns for equilibrium, it's suggested to manipulate the equations to eliminate variables. A recommended approach is to add specific equations, such as equations (1) and (3), to simplify the problem. This method can help in progressing towards a solution. The original poster successfully solved the equations after applying this technique. Overall, strategic manipulation of the equations is key to finding the solution.

how did they solve 1 through 4? it should be easy but i can't solve it :frown:

thanks for any help

You want to manipulate the equations to eliminate variables. For example, what happens if you add equations (1) and (3) together? Try this and see if you can proceed further.
 
ok thanks i solved it
 
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...
