A pоint chаrge Q mоves оn the x-аxis in the positive direction with а speed of 280 m/s. Consider a point P that is on the y-axis at y = 70 mm. As the charge moves through the origin, the magnetic field observed at P is -0.30 x10-6 k^ T. What is the charge Q? Hint: You get the sign of the charge from the direction of the cross product in Biot-Savart. μ0 = 4π × 10-7 T ∙ m/A
