Approximate the strong force between two protons.

AI Thread Summary
To approximate the strong force between two protons in a Helium nucleus separated by 2x10^-15 m, the strong force is considered to be about 100 times stronger than the electromagnetic force. The discussion suggests calculating the electromagnetic force between the protons using the Coulomb's law and then multiplying that value by 100 to estimate the strong force. It is noted that the strong force must balance the electromagnetic repulsion to maintain equilibrium within the nucleus. The concept emphasizes the critical role of the strong force in holding the nucleus together against the repulsive forces between protons. Understanding this relationship is essential for grasping nuclear stability.

Homework Statement


2 protons in a Helium nucleus are separated by about 2x10^-15 m. Calculate the approximate magnitude of the strong force holding the 2 protons together.

Homework Equations


Electromagnetic force equation?

The Attempt at a Solution


Okay now I am thinking that the strong force is 100 times stronger thn the electromagnetic force.. SO do I calculate the electromagnetic force between two protons and multiply by 100?

You know that strong force keeps the nucleus together, then the system must be in equilibrium, then the strong force must be equal to the coulomb force between the protons
 

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...
