1. The problem statement, all variables and given/known data [Broken] Answer is B. [Broken] Answer is E. [Broken] Answer is E. 2. Relevant equations E=F/q E=V/d Right hand rule for inductors 3. The attempt at a solution Quite confused for these problems. For number 18, I'm quite baffled as to where the 0.04 meters even comes from. What I had attempted to do was find the potential at the point, 25 V, and divide it by the radius, or √(.15^2+.08^2), but that didn't even yield one of the answers. Then I realized that the potential was actually increasing as x increased, and that the object causing the electric field was likely off the graph. Then I just got really confused. For number 33, I thought it was C. As the switch is flipped, there is a sudden increase in current in the top loop. This current flows out of the positive terminal, through the resistor, and back to the negative terminal. Since the current flows from left to right near the wire loop, the magnetic field generated should be into the page, right? Thus, to counteract this, a current that is counterclockwise will be generated in the loop. Unless I did the right hand rule wrong, that's what it should be. But the answer is E. For number 35, I don't really understand what the question is asking. I've never learned about the frequency and oscillating of the current in a circuit, with just a LC circuit. Utterly confused here. Would greatly appreciate any help! Thanks in advance!
