(Answer in degrees.) 9 part 2) in a region where the magnetic field is 3.78 T. It accelerates at 3.20 x 10 ms Ittne magnetic field is North and a deuteron (a particle comprising a neutron and a proton) is travelling downwards, in what direction is the magnetic torce on the deuteron? (No answer given) part 3) An electron has velocity i,' = Check x 105i + 2.8 x 1055) ms—I. A magnetic field B = 1.5i + 2.3j T. Give an expression tor the force F on the electron due to the magnetic field.

Newton's first and second law F = ma. ma = qvB sin(9) —1 ma 9 = sin qvB Marks for this submissiom 0.00/0.33. This submission attracted a penalty of 0.11 Feedback tor Part 2) F = x B, where q is positive. B is north, is down, so F is East. It the thumb ot your right hand is in the direction ot ä and your right index finger in the bdirection, then the middle finger ot that hand, fat right angles to the others, is in the direction otä x b.
