A free electron is placed in the path of a plane electromagnetic wave. The electron will start moving

Question

A free electron is placed in the path of a plane electromagnetic wave. The electron will start moving (A) along the electric field (B) along the magnetic field (C) along the direction of propagation of wave (D) in a plane containing the magnetic field and the direction of propagation

Tardigrade Admin · Accepted Answer

Electromagnetic wave contains both electric and magnetic field. When electron is placed, it experience force due to electric field because of which it start moving along the electric field. Force due to magnetic field is zero.
