Question

[1 point] A negatively charged particle has a velocity in the negative z-direction at point P. The magnetic force on the particle at this point is in the negative y-direction. Which of the following statements about the magnetic field at point P can be determined from this data? [Notation: "B"represents the magnitude of the component of the magnetic field in the i-tih direction.] 1.) What information can be deduced about B,? a. Br is negative. b. B is positive. c. Bx is zero. d. No information can be deduced about B 2.) What information can be deduced about B,7 e. By is negative. f. By is positive. g, B, is zero. h. No information can be deduced about By 3.) What information can be deduced about B? i. B is negative. j. Bz is positive. k. Bz is zero. 1. No information can be deduced about B ero ion c 12 points; see below] A proton is moving with velocity T (6.9x10 t+ 5.2x10 R The instant it enters a uniform magnetic field it experiences a magnetic force in the positive y direction of 29x10-6) N. 4A) To begin, compose an equality for this problem given F qixB, such that each of the vectors is expressed as vector sum of perpendicular (x/y/z) components. For example, 4.) [0.5 point] If there is no x component of the magnetic field (B, - 0), what is the y- component (By ?) of the magnetic field? 5.) [0.5 point] What is the direction of the z-component of the magnetic field? a. positive z-direction b. negative z-direction 6.) [1 point] What is the magnitude of the z-component of the magnetic field? (Please omit the factor "108 in your entered clicker answer.)
