Janessa got through high school easily because she could remember what her teachers said in class and their tests never covered anything else. but in college she is struggling with how to study more complex material, how to prepare for exams that demand that she apply what she is learning, and how to reconcile the apparent conflicts between what she learns in one course and what she learns in another. janessa's concerns fall into which domain?

CorrectThe direction of the electric field stays the same regardless of the sign of the charges that are free to move in theconductor.Mathematically, you can see that this must be true since the expression you derived for the electric field isindependent of .Physically, this is because the force due to the magnetic field changes sign as well and causes positive charges tomove in the direction (as opposed to pushing negative charges in the direction). Therefore the result isalways the same: positive charges on the side and negative charges on the side. Because the electric fieldgoes from positive to negative charges will always point in the direction (given the original directions of
