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 61500 V and then enters a region in which there is a uniform magnetic field of 0 . 51 T at right angles to the direction of the electrons motion. The mass of the electron is 9 . 11 10 31 kg and its charge is 1 . 60218 10 19 C. What is the magnitude of the force on the electron due to the magnetic field? Answer in units of N. 002 10.0 points A negatively charged particle moving paral- lel to the y-axis enters a magnetic field (point- ing toward the left-hand side of the page), as shown in the figure below. y z v x vector B vector B- q Figure: is in the x-direction, is in the y-direction, and k is in the z-direction. What is the initial direction of deflection? 1. hatwide F = + 2. hatwide F = + k 3. hatwide F =- k 4. hatwide F = + 5. vector F = 0 ; no deflection 6. hatwide F =- 7. hatwide F =- 003 (part 1 of 2) 10.0 points A proton moves perpendicularly to a uniform magnetic field, B , with a speed of 2 . 6 10 7 m/s and experiences an acceleration of 3 . 5 10 13 m / s 2 in the positive x direction when its velocity is in the positive z direction....
