The discussion revolves around determining the values of Q1 for points A, B, and C in a physics problem, specifically focusing on the values assigned to AB, AC, and CB. The original poster notes specific values at points A, B, and C and questions the reasoning behind the assigned Q1 values.
The discussion is ongoing, with participants expressing confusion and seeking further explanations regarding the initial guesses for Q1 values. Some guidance has been offered regarding the iterative nature of the method used to arrive at these values, but no consensus has been reached.
Participants are questioning the assumptions made in the problem, such as the choice of positive and negative directions for the values, and the implications of selecting different initial guesses for the Q1 values.
can someone show Q1 for AB is 5 ? for Ac is -5 , while for CB is -2 ?foo9008 said:
It's a problem when you reply to your own post that other readers think you've had a reply unless they follow the link to the thread.foo9008 said:
It's only a trial solution. Any values could have been used that add up correctly.foo9008 said:
what do you mean by trial solution ? I'm confused... how did the author get the Q= 5, -5 , and -2 based on 10 , 3 and 7 ?haruspex said:
I mean it is just an initial guess, consistent with the 10, 3 and 7. The method goes through an iteration to get closer to the actual solution. As an exercise, you could start with 6, -4 and -1 instead and check that you end up with the same final answer.foo9008 said:
is there any rule to choose the 3 numbers for initial guess? e.g , if i choose the first number is 15 , will it affect the second and third number that i am choosing ? or it is just guessing ?haruspex said:
