A physical distance can mean several different things: Distance traveled: The length of a specific path traveled between two points, such as the distance walked while navigating a maze Straight-line (Euclidean) distance: The length of the shortest possible path through space, between two points, that could be taken if there were no obstacles (usually formalized as Euclidean distance) Line L has intercepts a and b on the coordinate axes. If using this purple line, you draw a line from the red dot to its meeting point, and a line from the red dot to the blue dot. Furthermore,the slope of this line is the unknown exponent n in equation 5.1. The charge Q is spread uniformly over the line, which has length L.
