Can the pset/CyberTutor deadline be Friday?
You’ll have to ask Prof. Roland. Content Questions I’m confused about the difference between field vectors and field lines. Field lines and vectors are different tools for visualizing electric fields (and other kinds of fields). You can think of field vectors as vectors attached to every point in space, where the vector at each point gives the field (e.g. electric field) magnitude and direction at that point. A vector can have only one direction. A field line, on the other hand, is a continuous line that could change direction (it can snake around, although it might be straight, too). It’s the line tangent to the electric field vectors at every point. So, imagine drawing the electric field vectors in space. Then, draw a line that connects the points such that it’s always tangent to field vectors- that’s the field line. Because a field line is a continuous line, it doesn’t have a magnitude, but density of field lines tells you about the magnitude of the field.
