1. The problem statement, all variables and given/known data An electron experiences the greatest force as it travels 2.9 x 10^6 ms in a magnetic field when it is moving northward. The force is upward and of magnitude 7.2 x 10^-13 N. What are the magnitude and direction of the magnetic field? 2. Relevant equations 3. The attempt at a solution I don't even know how to get a diagram going for this. Anything would be helpful. Thank you.
