Any answers NOT recorded on the Scantron answer page will NOT be counted gitate me The uniform magnetic field B in the diagram has a magnitude of 75 T and a direction of 35 degrees with respect to the y-axis. An electron is traveling parallel to the y-axis at a velocity of 8.5 x 10' m/s. 17. What is the angle between the velocity and the magnetic field? A) 0° B) 35° C)55 D) 90 E) 180 18. What is the magnitude of the magnetic force on the electron? A)-1.88 × 10-11 N B)2.24x10" N 03.15xio-10 ND) 427x10-10 N E) 586 x 10-10 N 19. What is the direction of the magnetic force on the electron? A) right B) left C) up D) down E) into the page F) out of the page

Explanation / Answer

17) B) 35 degrees

18) E) 5.86*10^-10 N

F = q*v*B*sin(theta)

= 1.6*10^-19*8.5*10^7*75*sin(35)

= 5.86*10^-12 N

19) F) out of the page
