In a magnetic field with induction B = 2T, an electron moves at a speed of 10 ^ 6 m / s, directed perpendicular

In a magnetic field with induction B = 2T, an electron moves at a speed of 10 ^ 6 m / s, directed perpendicular to the lines of induction of the magnetic field, which is equal to the modulus of force F acting on the electron from the side of the magnetic field.

The electron is acted upon by the Lorentz force FL, the absolute value of which is calculated by the formula:

FL = evB * sina,

where e is the electron charge, v is its velocity, B is the magnitude of the magnetic field induction, and is the angle between the direction of the velocity and the induction vector B. Angle a = 90 °, therefore sin a = 1:

FL = evB.

FL = 1.6 * 10 ^ (- 19) Cl * 10 ^ 6 m / s * 2 T = 3.2 * 10 ^ (- 13) N.

Answer: 3.2 * 10 ^ (- 13) N.
