Calculating Velocity for Horizontal Motion in a Uniform Magnetic Field

In summary, the question asks how fast a stone with a negative net charge of 0.010C needs to move in a uniform magnetic field with a strength of 1.70T in order to remain moving horizontally without any vertical deviation. The stone travels perpendicular to the force, so there will be vertical deviation regardless of velocity. However, the question's diagram shows the magnetic field pointing into the page, so it may be a "trick" question.

Homework Statement


A stone with a negative net charge of 0.010C is given a constant horizontal motion in a uniform magnetic field in the direction pointing into the page. The field's strength is 1.70T. How fast does the stone have to move in order for it to remain moving horizontally, without any vertical deviation?

The Attempt at a Solution


The stone travels perpendicular to the force, so I think regardless of velocity, there will be vertical deviation.

Yes, that seems right. :confused:

Maybe they intend you to lay the paper flat, so that the B field is pointing downwards?

The question's diagram shows the magnetic field pointing into page, so I suppose its a "trick" question. Nevertheless, thank you for your help. I spent a long time looking at this because its the last question on the list.
 

1. What is a uniform magnetic field?

A uniform magnetic field is a type of magnetic field in which the strength and direction of the magnetic field remains constant at all points. This means that the field lines are parallel and equally spaced, creating a uniform pattern.

2. How is a uniform magnetic field created?

A uniform magnetic field can be created by passing an electric current through a straight wire, using a bar magnet, or using electromagnets. These methods produce a uniform magnetic field within a certain region surrounding the source of the field.

3. What are some real-world applications of a uniform magnetic field?

Uniform magnetic fields are used in many everyday devices, such as electric motors, generators, MRI machines, and particle accelerators. They are also used in scientific research to study the behavior of particles in a controlled magnetic environment.

4. How does a uniform magnetic field affect charged particles?

A uniform magnetic field exerts a force on a charged particle that is perpendicular to both the direction of the magnetic field and the velocity of the particle. This causes the particle to move in a circular path, with the radius of the circle depending on the strength of the magnetic field and the speed of the particle.

5. Can a uniform magnetic field be shielded or blocked?

Unlike electric fields, magnetic fields cannot be easily shielded or blocked. Some materials, such as mu-metal, can redirect the magnetic field lines, but a uniform magnetic field cannot be completely blocked. However, the strength of the field can be weakened by increasing the distance from the source.
