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 3.15 102 m/s at an angle 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 2.35 10-7 N. Find the angle . (There are two possible angles.)
° (smaller angle)
° (larger angle)

    F=qv x B in vectors

    so

    sinTheta=F/qvB

    and remember your trig identies:

    sinTheta= sin(180-Theta) as I recall...

    For instance, Sin 87= sin 93
