Question: An electron moves with a speed of 5.0 x 104 m/s perpendicular to a uniform magnetic field of 0.20T.
Part I: What is the magnitude of 0.20 T.
Part II: What is the magnitude of magnetic force on the electron?
(Given q=1.6 x 10-19 C, m=9.11 x 10-31kg).
If possible just a brief explanation how you got the answer?
