# Problem: A proton moves along the x-axis with vx=1.0 × 107 m/s.a) As it passes the origin, what are the strength and direction of the magnetic field at the (0 cm, 1 cm, 0 cm) position? Express your answer in terms of the unit vectors î, ĵ, and k̂.b) As it passes the origin, what are the strength and direction of the magnetic field at the (0 cm, -2 cm, 0 cm) position? Express your answer in terms of the unit vectors î, ĵ, and k̂.

A proton moves along the x-axis with vx=1.0 x 10m/s.

a)

μ0 = 4π × 10-7 T•m/A

v = vx =1.0 x 10m/s

q = 1.6 x 10-19 C

r = 1 cm = 0.01 m
