To determine the effect of the wire on the charged particle, we need to analyze the interaction between the current-carrying wire and the moving particle.
In the given figure, the wire carries current in the positive x direction, and the charged particle has an initial velocity in the negative y direction. We can consider two factors in determining the effect on the charged particle:
1. Magnetic Field: A current-carrying wire generates a magnetic field around it. According to the right-hand rule, if we point the right thumb in the direction of the current (positive x direction), the curling fingers will give us the direction of the magnetic field. In this case, the magnetic field around the wire will be in the counterclockwise direction (B̂).
2. Lorentz Force: When a charged particle moves in the presence of a magnetic field, it experiences a force due to the interaction between its velocity and the magnetic field. This force is called the Lorentz force.
Using the right-hand rule again, we can determine the direction of the Lorentz force acting on the charged particle. We point the right thumb in the direction of the charged particle's velocity (negative y direction) and the curled fingers in the direction of the magnetic field (counterclockwise around the wire). The resulting force will be in the positive x direction (F̂).
Therefore, the charged particle experiences a force in the positive x direction when it has an initial velocity in the negative y direction.
Please note that the magnitude of the force experienced by the charged particle depends on the strength of the current, the distance from the wire, and the charge of the particle.
