Question

A charged particle is in a region that contains both an electric and a magnetic field. The kinetic energy of the particle increases as it moves from point X to point Y. What can be concluded with certainty?

Answer 1

he electric field and the magnetic field are PARALLELS

Step-by-step explanation:

The charged particle is subjected to two forces, the electric force and the magnetic force. The electric force is in the direction of the electric field and creates an acceleration n of the particle, instead the magnetic force creates a force perpendicular to the velocity and the magnetic field.

Therefore, for the particle to show an acceleration the magnetic force must be in the direction of the electric force, by local the magnetic field must be parallel to the electric camp, therefore between the velocity and the magnetic field the Angle is to be, that is to say there is no magnetic force

In summaryt he electric field and the magnetic field are PARALLELS
