Multiplechoice 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 . 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 protons acceleration? Answer in units of m / s 2 . 004 10.0 points A positively charged particle moving paral lel to the xaxis enters a magnetic field (point ing toward the lefthand side of the page), as shown in the figure below. x y v z vector B vector B + q Figure: is in the xdirection, is in the ydirection, and k is in the zdirection.
