Задача 30452.

Determine the magnitude and direction of the velocity of an electron beam that does not experience any deviation in uniform electric (E = 0.7 kV/m) and magnetic (B = 0.35 mT) fields crossed at right angles. What radius of circle will the electrons move along if the electric field is removed?

Detailed solution with a brief entry of the condition, formulas and laws used in the solution, derivation of the calculation formula and the answer. If you have any questions about the solution, write. I will try to help.
