Question 1 A proton travels at a speed of 6.53x10' m/s along the x-axis. What is the magnetic field at the point (0.00 cm, -7.00 cm, 0.00 cm) when the proton passes through the origin? O -2.61x10 92 KT O 2.13 x10-16 KT O -2.13x10-16 KT O 2.61x10 32 KT Question 2 The figure shows a closed surface that has a line integral of the magnetic field of 1.00*10" Tm. If /, = 2.30 A and /2 = 6.00 A. what is the current flowing through ? O 6.80 A O 1.50 A O 4.50 A O 7.50 A Question 3 An electron travels through a magnetic field with a strength of 2.40 T and is traveling at a speed of 4.83x10' m/s. What is the force on the electron as shown in the figure? O 1.31x10-11 (j + k) N O 1.85 x 10 11 (j + k) N O 1.85 10-11 (-j - k) N O 1.31x10-11 (-j - k) N
