In a lightening bolt, current travels upward, from ground to cloud.Suppose that at the moment that a 35,000; A lightening bolt is formed in the atmosphere, an airplane was 1.5m away and flying directly away from the bolt%u2019s location at a speed of 240m/s in the +x direction, as shown. If the airplane has obtained a net charge of ;15C from the electrically;charged air, what is the magnitude and direction of the magnetic force on the airplane?
