[SOLVED] Deflection of beam due to magnetic field 1. The problem statement, all variables and given/known data In the electron gun of a TV picture tube the electrons (charge - e, mass m) are accelerated by a voltage V. After leaving the electron gun, the electron beam travels a distance D to the screen; in this region there is a transverse magnetic field of magnitude B and no electric field. Find the approximate deflection of the beam due to this magnetic field. (Hint: Place the origin at the center of the electron beam’s arc and compare an undeflected beam’s path to the deflected beam’s path.) Express your answer in terms of the variables B, D, e, m, and V. 2. Relevant equations E/B = ((2eV)/m) e/m = 1.758E-11 C/kg 3. The attempt at a solution I would show my work, but I really have no idea how to. I tried just typing in the equation for E/B, but it didn't work. Is there a specific formula for deflection?
