A point charge Q moves on the x-axis in the positive direction with a speed of 170 m/s. A point P is on the y-axis at y = +30 mm. The magnetic field produced at point P, as the charge moves through the origin, is equal to -0.7 μT k^. When the charge is at x = +40 mm, what is the magnitude of the magnetic field at point P? (μ 0 = 4π × 10-7 T · m/A)
