luu (nml299) – HW07 – markert – (58710) 1 This print-out should have 22 questions. Multiple-choice questions may continue on the next column or page – find all choices before answering. 001 10.0 points Two parallel wires carry opposite current as shown. i 1 i 2 Find the direction of the magnetic force on i 2 due to the magnetic field of i 1 . 1. to the right 2. out of the paper 3. into the paper 4. to the right and downward 5. to the left and downward 6. to the right and upward 7. to the left 8. to the left and upward 002 (part 1 of 2) 10.0 points A proton travels with a speed of 3 . 46 × 10 6 m / s at an angle of 18 . 6 with a magnetic field of 0 . 183 T pointed in the y direction. The charge of proton is 1 . 60218 × 10 19 C. What is the magnitude of the magnetic force on the proton? Answer in units of N. 003 (part 2 of 2) 10.0 points The mass of proton is 1 . 67262 × 10 27 kg What is the proton’s acceleration? Answer in units of m / s 2 . 004 10.0 points A positively charged particle moving paral- lel to the x -axis enters a magnetic field (point- ing toward the left-hand side of the page), as shown in the figure below. x y v z vector B vector B + q Figure: ˆ ı is in the x -direction, ˆ is in the y -direction, and ˆ k is in the z -direction. What is the initial direction of deflection? 1. hatwide F = ˆ 2. hatwide F = + ˆ k 3. hatwide F = ˆ k 4. hatwide F = ˆ ı 5. vector F = 0 ; no deflection 6. hatwide F = +ˆ 7. hatwide F = +ˆ ı 005 10.0 points A positively charged particle moving at 45 angles to both the x -axis and y -axis enters a magnetic field (pointing out of of the page), as shown in the figure below.
