Multiplechoice questions may continue on the next column or page find all choices before answering. The due time is Central time. 001 (part 1 of 1) 10 points Find the magnitude of the magnetic force on a proton moving with velocity 4 . 31 Mm / s in the positive x direction in a magnetic field of 1 . 65 T in the positive z direction. Correct answer: 1 . 13939 pN. Explanation: Let : q = 1 . 60218 10 19 C , ~v = (4 . 31 Mm / s) = (4 . 31 10 6 m / s) , and ~ B = (1 . 65 T) k . ~ F = q~v ~ B = (1 . 60218 10 19 C) (4 . 31 10 6 m / s) / h (1 . 65 T) k i 10 12 pN 1 N = (1 . 13939 pN) , so the magnitude is 1 . 13939 pN . keywords: 002 (part 1 of 1) 10 points A straight wire segment 2 m long makes an angle of 30 with a uniform magnetic field of . 33 T. Find the magnitude of the force on the wire if it carries a current of 2 . 7 A. Correct answer: 0 . 891 N....
