Particle's Movement in a Uniform Electric Field

In summary, a particle with a mass of 1.5×10−5kg and a charge of +2.9 μC is released in a uniform horizontal electric field of 11 N/C. The question asks for the horizontal distance traveled in 0.40 seconds. To solve this, the acceleration of the particle must be found, which can be done using Newton's second law.

Homework Statement


A particle with a mass of 1.5×10−5kg and a charge of +2.9 μC is released in a (parallel plate) uniform horizontal electric field of 11 N/C .

How far horizontally does the particle travel in 0.40 s ?

Homework Equations


I think some of the kinematic equations are needed, but it's been so long since I took that part of physics, I'm not sure which one to use![/B]

The Attempt at a Solution


I don't even know where to start. I think I have to find the particle's acceleration first, but I'm not even sure how to do that![/B]

Getting the acceleration sounds like a good idea. How about using Newton's second law?
 

FAQ: Particle's Movement in a Uniform Electric Field

What is a uniform electric field?

A uniform electric field is a type of electric field where the strength and direction of the field are constant throughout the space. This means that the electric field lines are parallel and evenly spaced.

How does a particle move in a uniform electric field?

A particle in a uniform electric field will experience a force in the direction of the field. The magnitude of this force depends on the charge of the particle and the strength of the electric field. The particle will accelerate in the direction of the force and its trajectory will be a parabolic curve.

What is the relationship between the electric field and the particle's acceleration?

The particle's acceleration is directly proportional to the strength of the electric field and the charge of the particle. This relationship is described by the equation a = qE/m, where a is the acceleration, q is the charge of the particle, E is the electric field strength, and m is the mass of the particle.

How does the charge of the particle affect its movement in a uniform electric field?

The charge of the particle determines the magnitude of the force it experiences in the electric field. A particle with a larger charge will experience a stronger force and therefore accelerate more than a particle with a smaller charge. Additionally, particles with opposite charges will move in opposite directions in the same electric field.

Can a particle's movement in a uniform electric field be affected by other forces?

Yes, a particle's movement in a uniform electric field can be affected by other forces, such as gravitational force or magnetic force. In such cases, the particle's trajectory will be a combination of the effects of all the forces acting on it.
