Question

A point charge Q moves on the x-axis in the positive direction with a speed of 160 m/s. A point P is on the y-axis at y = +20 mm. The magnetic field produced at the point P, as the charge moves through the origin, is equal to -0.6 μT k^k^. What is the charge Q? (μ 0 = 4π × 10-7 T · m/A)

Answer 1

Answer:

The charge on the particle = -0.00075 C = -0.75 mC = -750 μC

Explanation:

The solution to this question is presented in the attached image to this answer.

The Biot Savart's formula for calculating magnetic field due to moving point charge is used in this calculation.
