Hi, I'm having trouble figuring out one of my homework questions. It says
" The total charge on two charged objects is Q. What must the charges on each of them be, in order that the force between them is (a) maximum and (b) minimum.Thanks guys.

Hi deldel, one of the rules of Physics Forums is that we're not allowed to offer help with homework questions until you provide evidence of your attempt to find the answer yourself. That's why the template is provided for homework questions.
 
Oh, sorry about that
 
Hi deldel, Welcome to Physics Forums!

I'm closing this thread as it lacks the template and an attempt at solution.

@deldel , please start a new thread and use the template provided if you would like to pursue this question further.

Thanks for participating in Physics Forums!
 
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...
