Electric fields between point charges

AI Thread Summary
The discussion centers on the convention of referencing angles in relation to the positive x-axis rather than the y-axis when analyzing electric fields between point charges. Participants emphasize the need for clarity in terminology, suggesting that the phrase "angle from the line AP" is more accurate than "to the line AP." This focus on precision in language highlights the importance of standard conventions in physics. The repeated mention of these points underscores a shared understanding of the conventions used in vector analysis. Overall, the conversation reflects a commitment to clear communication in scientific discussions.

Homework Statement
Question 2c: I've attempted the question, I've got the magnitude right but I got the angle wrong. I don't understand why the value of the components are swapped around.

I’m guessing it’s just convention to reference the angle from the positive x-axis instead of the y-axis.

To nitpick your solution should say “angle from the line AP” not “to the line AP”

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 '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...

Thread 'Trying to understand the logic behind adding vectors with an angle between them'

Thread 'Trying to understand the logic behind adding vectors with an angle between them'

My initial calculation was to subtract V1 from V2 to show that from the perspective of the second aircraft the first one is -300km/h. So i checked with ChatGPT and it said I cant just subtract them because I have an angle between them. So I dont understand the reasoning of it. Like why should a velocity be dependent on an angle? I was thinking about how it would look like if the planes where parallel to each other, and then how it look like if one is turning away and I dont see it. Since...
