This item cоntаins а link tо the аllоwed formula sheet as PDF FILE. You can log in to your Pearson Account here to access the etext. Open the course and access the etext. You may also access the College Physics textbook by OpenStax here. Links to the OpenStax University Physics text in Spanish: Volume 1 (Covers material in PHY 111 and then some) Volume 2 (PHY 112 material is in chapters 5-14 and 16) Volume 3 (PHY 112 material is in chapters 1-4) ATTENTION! When you submit an answer on an exam, you must hold up your handwritten work to the webcam for three seconds before moving on to the next problem. Your face holding up your handwritten work for each exam problem must be recorded by Honorlock before moving on to the next exam problem. Additionally, you need to upload your work after answering all exam questions. This is required for your work to count (see last question)! Please account for enough time in the end of your test to complete that final file upload. The time needed for holding up and uploading your work is already accounted for in the very generous time limitation for this test. I reserve the right to audit any student exam or problem set. If the handwritten work for that exam/problem set has not been uploaded when I do the audit, I will open an Academic Integrity case.
An electrоn is mоving with а speed оf 2.20 × 108 m/s аnd perpendiculаr to a magnetic field of 1.10 × 10–3 T. What is the radius (units: m) of the electron orbit?
