What is the force experienced by a charged particle moving perpendicular to an electric field? I understand that when it is moving parallel to the electric field, it accelerates.
When a charged particle is at rest in an electric field, it experiences a force in the direction of electric field (if it is a positive charge)
If it is moving in the direction of electric field, it will be accelerated.
If it is moving opposite to the electric field, it will be decelerated.
If it is moving perpendicular to the electric field, its trajectory will be a parabola, similar to that of a horizontal projectile
