Force on charged particle to enter electric field perpendicularly

In summary, the conversation discusses the amount of force needed to make a charged particle enter an electric field perpendicularly, specifically in the context of a charged capacitor. It is stated that a charged particle cannot enter a field perpendicularly as it would orbit the field. It is also mentioned that if the particle is already in the field, no external force is required to move it perpendicularly. The conversation also touches on edge effects in a real capacitor and the potential need for a large force to enter the field perpendicularly.

how much force, if at all. is required to make a particle enter an electric field perpendicularly...
eg, to let a charged particle enter a charged capacitor perpendicularly, is external force required??

I don't think a charged particle CAN enter a field perpendicularly. If it is always perpendicular to the field then it would orbit the field.

If it was already in the field within the capacitor then it shouldn't take any force to move it, at a constant velocity, perpendicular to the field.

what does this mean,"if it is always perpendicular to the field then it would orbit the field."...why?

If your perpendicular to the field exiting the charged object then you are going around it considering it is a point object which all electric objects are from an outside the field point of view.

In a real capacitor, edge effects cannot be ignored and so a reasonably large force would be required to enter the region perpendicularly, since the charged particle would be attracted to the appropriate plate.
 

1. What is the force experienced by a charged particle when it enters an electric field perpendicularly?

The force experienced by a charged particle when it enters an electric field perpendicularly is known as the Lorentz force. It is given by the equation F = qE, where q is the charge of the particle and E is the electric field strength.

2. How is the direction of the force on a charged particle determined when entering an electric field perpendicularly?

The direction of the force on a charged particle when entering an electric field perpendicularly is determined by the right-hand rule. If the particle has a positive charge, the force will be in the direction of the electric field. If the particle has a negative charge, the force will be in the opposite direction of the electric field.

3. What factors affect the magnitude of the force on a charged particle when it enters an electric field perpendicularly?

The magnitude of the force on a charged particle when it enters an electric field perpendicularly is affected by the charge of the particle, the strength of the electric field, and the velocity of the particle. The force will also increase if the particle has a greater mass.

4. Can the force on a charged particle be zero when it enters an electric field perpendicularly?

No, the force on a charged particle cannot be zero when it enters an electric field perpendicularly. This is because the electric field will always exert a force on the particle due to its charge. However, the particle may have an initial velocity that is parallel to the electric field, causing the net force to be zero.

5. How does the force on a charged particle entering an electric field perpendicularly affect its motion?

The force on a charged particle entering an electric field perpendicularly will cause the particle to accelerate in the direction of the force. If the particle's initial velocity is perpendicular to the electric field, it will move in a circular path. If the initial velocity is not perpendicular, the particle will move in a curved path. The force will continue to act on the particle, causing it to change direction and accelerate as it moves through the electric field.
