AI Thread Summary
To demonstrate the spring constant k in Hook's Law, a vertical spring setup can be used with a mass hung at the end. By measuring the stretch of the spring and the force applied (the weight of the mass), multiple trials with different masses can be conducted. This data allows for the plotting of a graph of force (F) versus displacement (x). The slope of this graph remains constant and is equal to the spring constant k. This experimental approach effectively illustrates the relationship defined by Hook's Law.

How to demostrate k in Hook' s law?
 
Physics news on Phys.org
Experimentally, you could probably use a spring setup where a spring is suspended vertically, and a mass is hung at the end. You measure the length of stretch of the spring, as well as the force applied to it (which is the weight of the mass). Doing multiple trials with different masses will give you enough data to plot a graph of F vs. x. You will notice that the slope of this line is constant, and it is equal to k.
 

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...

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 .
