Hello everyone!

My question is simple. Is there some website with really good and tricky physics exercises? I'm in 12th grade but I have also been studying and practicing by myself for some time now. I need 12th grade topics but with harder level questions. Any ideas would be great...

Thanks a lot.

But hey, I meant hard but not that hard. Can you lower the bar a little bit more? Also, any good books with the types of problems discribed that are mentioned would be appreciated. Thanks.
 

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...
