🤓 Based on our data, we think this question is relevant for Professor Ford's class at TAMU.

Solution: A particle having a mass of 0.195 g carries a charge of -2.50x10 -8 C. The particle is given an initial horizontal northward velocity of 4.00x10 4 m/s. What are the magnitude and direction of the minimum magnetic field that will balance the Earth's gravitational pull on the particle? Hint: The velocity and the gravitational force are perpendicular.
