Question 1 An electron travels at a speed of 6.49x107 m/s along the z-axis. What is the magnetic field at the point (0.00 cm,6.00 cm,6.00cm) when the electron passes through the origin? O 2.04x10-16 T, O 1.02x10-16 T, 0-2.04x10-16 T -1.0210-16 i Question 2 10 em path Determine the value for the line integral of the magnetic field between pointsiand f. The current through the wire is 8.60 A and the distance between pointsiand fis 6.20 cm. 1.62x10-3 Tm 5.40x10-6 Tm 1.08x10-5 Tm 8.84x106 Tm Question 3 IOA 2 What is the net force on wire number 3? The wires are spaced 3.60 cm apart and they are 34.0 cm long. 0.000283 N, down 0.000283 N, up 9.44 10 5 N, down O 9.44x10-5 N, up

Explanation / Answer

1] magnetic field due to moving charge B = u0/4pi q v x r^ /r^2

= 1*10^-7 *-1.6e-19*6.49e7*sin 45 degree / (0.06^2+0.06^2)

= -1.02*10^-16 i T

last option is correct
