Due to friction with the air, an airplane has acquired a net charge of 1.70 10-5 C. The plane moves with a speed of 2.90 102 m/s at an angle θ with respect to the earth's magnetic field, the magnitude of which is 5.00 10-5 T. The magnetic force on the airplane has a magnitude of 2.30 10-7 N. Find the angle θ. (There are two possible angles.)
- (smaller angle)
- (larger angle)
