An electron flies into a uniform magnetic field with an induction of 2 T at a speed of 10M m / s, directed perpendicular to the vector b. Find the force acting on the electron.

m = 9.1 * 10 ^ -31 kg.

q = 1.6 * 10 ^ -19 Cl.

V = 10 Mm / s = 10 * 10 ^ 6 m / s.

B = 2 T.

∠α = 90 °.

Flor -?

On a charged particle with a charge q, which moves with a speed V, in a magnetic field by induction B, the Lorentz force acts, the value of which is determined by the formula: Flor = q * V * B * sinα, where ∠α is the angle between the speed V and the magnetic induction B.

Since an electron is a charged particle, its charge is q = 1.6 * 10 ^ -19 C.

Flor = 1.6 * 10 ^ -19 C * 10 * 10 ^ 6 m / s * 2 T * sin90 ° = 32 * 10 ^ -13 N.

Answer: the electron is acted upon by the Lorentz force Flor = 32 * 10 ^ -13 N.
