Provided in the questions I believe. Here's the triangle from question two.
The Attempt at a Solution
QUESTION SET 1 TOP OF PICTURE
A.) I didn't know how to just "guess" what the constant should be so I actually worked it out. I found the constant to be
c=[itex] \mu [/itex] 0 I 0 / [itex] 4 \pi [/itex]
But how would I just know as they want me to?
B.) I'm fine on this one.
C.) I think I'm fine on this one, and we're told to skip it. However, I believe it will grow linearly until it hits the edge of the wire then drop to zero.
Extra Question not shown: Is the answer unique?
I don't know how I'm supposed to know that with what's given. I know we can add any arbitrary constant we want for any vector potential (or so I was told) but I'm not really sure how to approach this part.
QUESTION SET 2 BOTTOM OF PICTURE
A.) I used the most general form for Biot-Savart law:
I'll wait to work on B since I think my part A is wrong.
Thanks in advance to any an all who give some help on this. :D
