Net Force of A: Diagram Analysis
AI Thread Summary
To find the net force on object A, the relevant equations include the force between charges FAB=KqAqB/r², and the components of the forces Fx=Fcosθ and Fy=Fsinθ. The total force can be calculated using the formula FR=sqrt(Fx² + Fy²) and determining the angle θ with θ=tan⁻¹(Fy/Fx). Participants are encouraged to calculate the vector forces F_AB and F_AC, then sum these vectors to obtain the total force acting on A. Providing the calculations will help clarify the process.

You need to find the vector forces ## F_{AB} ## and ## F_{AC} ## and sum those force vectors to get the total force on A. Can you show us your work on that?Spotify said:
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 .
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...
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...
