Question

An electron moves with constant velocity V parallel to the direction of uniform magnetic field B. The force experienced by the electron is):

Answer 1

Answer:

Force experience by the electron is zero, because F=qVB sin (0) , only electron go parallel with magnetic field when direction of velocity is parallel with magnetic field , that is angle is equal to zero. And sin of 0 is equal to zero.

In real life in uniform magnetic field a electron goes in a circular path.
