NAME PHYS-1200 PHYSICS II QUIZ 2 OCTOBER 24, 2001 SOLUTIONS PART A. 1. E 6. D 2. D 7. B 3. B 8. D 4. B 5. C PART B . 1. TO THE TOP OF THE PAGE The current in the wire produces a decreasing magnetic flux within the wire loop. According to Lenz’s law, the induced electric field would be in a direction to oppose that decrease. It must be counterclockwise about the loop, so at P , it is toward the top of the page. 2. a) TO THE LEFT The same direction as the current in the wires. b) INTO THE PAGE Based on the direction of the current and the right hand rule. 3. a) NO DIRECTION, IT IS ZERO That is the equilibrium position. b) TO THE RIGHT Back toward the equilibrium position. c) NO DIRECTION, IT IS ZERO That is the equilibrium position.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
