Задача 30466.

In a photograph taken in a cloud chamber placed in a magnetic field, the electron trajectory is an arc of a circle with a radius R = 10 cm. Magnetic field induction S = 10 mT. Find the kinetic energy of the electron in electron volts, the momentum and angular momentum of the electron relative to the center of curvature of the trajectory.

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