Calculating the theoretical force of repulsion between two magnets

AI Thread Summary
Calculating the theoretical force of repulsion between two magnets involves considering factors such as distance, relative orientation, and size. The discussion highlights that the formula for this force is complex and not straightforward. A referenced Wikipedia page provides examples of different magnet configurations. Participants clarify the relationship between force and distance, correcting terminology from "inverse exponential" to "inverse square." Understanding these principles is essential for accurate calculations in magnetism.

Homework Statement
I have been asked to complete a student experiment in which I decided to describe the inverse exponential relationship between the force of repulsion and the distance between two magnets.

I was wondering whether it be possible to calculate the theoretical value for the force at each distance?
Relevant Equations
I found this formula on the internet: F=K((m1m2)/((mu)xr^2))
Any help would be much appreciated! Thanks

Not only distance but relative NS direction angle and even size of magnet matter. The general formula between the magnets is rather complicated. The formula you referred is force between hypothetical magnet charges as if N and S were separable. https://en.wikipedia.org/wiki/Force_between_magnets shows some examples of various configurations.
 
Thankyou!

Inverse exponential!?
Inverse quadratic maybe.

Inverse square. My bad.
 

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...
