When a charged particle enters perpendicular to a magnetic field, the path followed by its:

Explanation

When a charged particle, such as an electron, enters a magnetic field perpendicularly (at a right angle) to the direction of the magnetic field lines, it follows a circular path due to the force exerted on it by the magnetic field. This circular path is a result of the interaction between the magnetic field and the moving charge, as described by the Lorentz force law. The Lorentz force law states that when a charged particle with charge q moves with a velocity v in a magnetic field B, it experiences a force F given by: F = q * (v x B) Where: F is the force vector experienced by the charged particle q is the charge of the particle v is the velocity vector of the particle B is the magnetic field vector When the charged particle enters the magnetic field perpendicular to the field lines, the force experienced by the particle is always perpendicular to its velocity. As a result, the magnetic force continuously changes the direction of the particle's motion, making it move in a circular path. The centripetal force required to keep the charged particle moving in a circle is provided by the magnetic force. The charged particle will continue to move in a circular path as long as it remains in the magnetic field and continues to move at a constant speed.
