Homework Help Overview

The discussion revolves around the relationship between force (F) and current (I) in a physics context, specifically questioning the graphical representation of this relationship. The original poster expresses confusion regarding the absence of a graph in their textbook, suggesting that F should be directly proportional to I based on the equation F = BIL sin(theta).

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • Participants explore the expected linear relationship between F and I, questioning the textbook's omission of a graph. There are inquiries about the validity of the textbook's answer and the reliability of hand-drawn sketches.

Discussion Status

The discussion is ongoing, with participants examining the implications of the textbook's content and the nature of the graph that should represent the relationship. Some guidance has been offered regarding how to approach drawing the graph, but there is no consensus on the textbook's accuracy.

Contextual Notes

There is mention of a potential lack of clarity in the textbook's presentation, including the possibility of a blank graph intended for student completion. The original poster has not provided the textbook's answer for further clarification.

Homework Statement



according to my book, there's no graph for F versus I , can someone expalin why? based on my understanding it should be a straight line graph ( directly propotional) since F= BIL SIN TETHA

For any given layout, F vs. I should be a sloping straight line. I see no evidence of your textbook implying otherwise.

You haven't shown the textbook's answer. (A hand-drawn sketch is not reliable.)

I guess your textbook is supplying a blank graph for you to fill in? Or maybe the author simply forgot to hand draw the graph before the book went to the printers.

Just draw in a straight line through the origin, of some general slope. If you were asked to indicate the slope, what expression would you write?
