Due to friction with the air, an airplane has acquired a net charge of 2 x 10-5 C. The plane moves with a speed of 2.83 x 102 m/s at an angle θ with respect to the earth's magnetic field, the magnitude of which is 5.01 x 10-5 T. The magnetic force on the airplane has a magnitude of 5.7 x 10-8 N. Find the angle θ.
There are two possible angles. Enter the one in the first quandrant. Enter "deg" as your units; for instance, if your answer is "45°" , enter "45 deg."
