(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

An electron moves with speed 9.50 105 m/s in a uniform magnetic field of 4.4 T, pointing south. At one instant, the electron experiences an upward magnetic force of 3.40 10-14 N. In what possible directions might the electron be moving at that instant? Give your answers as angles clockwise from south (from 0° to 360°), in increasing degrees.

2. Relevant equations

F=qB(vsin theta)

3. The attempt at a solution

I keep trying to plug all the knowns into this equation but i cannot seem to find the right answer.

3.4e-14=(1.6e-19)(4.4)(9.5e5sin theta) and find inverse.

the 2 answers should be clockwise from south
