AI Thread Summary
The discussion focuses on comparing the electric forces between helium and hydrogen nuclei at the same distance. The key difference lies in the number of protons in each nucleus, which directly affects the force exerted. More protons result in a stronger electric force due to increased charge. To quantify this difference, participants are advised to use the appropriate equation for electric force based on charge and distance. Understanding these principles is essential for solving the homework question effectively.

Homework Statement
how does the electric force between two helium nuclei placed a certain distance apart compare with the force between two hydrogen nuclei placed the same distance apart
Relevant Equations
would the forces be the same?
Not sure how I am suppose to solve this.

Welcome to the PF. :smile:

Since they are asking just about the nuclei and not neutral atoms, what is different about those two nuclei?
 
The amount of protons they have.
 
Correct! And why would that affect the forces between bare nuclei?

The more protons a nuclei has the more force they have.

Yes. Now all you have to do is quantify that difference in force in order to finish answering your schoolwork question. What is the equation for the force between two charges based on the amount of charge and their separation distance? That equation should be in your textbook or in your class notes. :smile:

Thread 'Struggling to make relation between elastic force and height'

Hello guys this is what I tried so far. I used the UTS to calculate the force it needs when the rope tears. My idea was to make a relationship/ function that would give me the force depending on height. Yeah i couldnt find a way to solve it. I also thought about how I could use hooks law (how it was given to me in my script) with the thought of instead of having two part of a rope id have one singular rope from the middle to the top where I could find the difference in height. But the...

Thread 'Voltmeter readings for this circuit with switches'

TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...
