hopkins (tlh982) – HW06 – criss – (4908) 1 This print-out should have 4 questions. Multiple-choice questions may continue on the next column or page – find all choices before answering. 001 10.0 points An electron in a vacuum is first accelerated by a voltage of 26300 V and then enters a region in which there is a uniform magnetic field of 0 . 104 T at right angles to the direction of the electron’s motion. What is the force on the electron due to the magnetic field? Answer in units of N. 002 10.0 points Sodium ions (Na + ) move at 0 . 794 m / s through a bloodstream in the arm of a person standing near a large magnet. The magnetic field has a strength of 0 . 26 T and makes an an- gle 67 . 1 with the motion of the sodium ions. The arm contains 73 . 5 cm 3 of blood (within the magnetic field) with 2 . 29 × 10 20 Na + / cm 3 . If no other ions were present in the arm, what would be the magnetic force on the arm? (Note: In fact, many oppositely charged ions also flow in the bloodstream, so the net force is considerably smaller than the number you

The loop is hinged along the y-axis, and its plane makes an angle oF 76 ◦ with the x-axis. A uniForm magnetic feld oF 0 . 51 T is di-rected along the x-axis and the current in the loop is 8 . 7 A in the direction shown. x y z 76 ◦ B = 0 . 51 T B = 0 . 51 T . 48 m 72 m i = 8 . 7 A What is the magnitude oF the torque ex-erted on the loop? Answer in units oF N · m. 004 10.0 points Because blood contains charged ions, moving blood develops a Hall voltage across the di-ameter oF an artery. A large artery with a diameter oF 1 cm has a ±ow speed oF 0 . 6 m / s. IF a section oF this artery is in a magnetic feld oF 0 . 3 T, what is the maximum possible potential di²erence across the diameter oF the artery? Answer in units oF mV....

    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.

    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.
