Charged particle Definition and 263 Threads

We have a particle with electric charge e that moves in a strong magnetic field B. The particle is constrained to the (x,y)-plane, and the magnetic field is orthogonal to the plane, and constant with B as the z-component of \mathbf{B}. Furthermore we have the rotationally symmetric form of the...

Does anyone know what were the methods suggested to contain charged particle beams in Reagan's Star Wars program and why did the suggested methods fail?

Right now I'm taking an introductory E&M class that uses Purcell's book "Electricity and Magnetism." The chapter we're covering focuses on deriving the Lorentz force law for moving charges using SR arguments. This is confusing because we've never covered SR before, so I have a lot of difficulty...

What physics is required to analyze the motion and dynamics of a charged particle beam? Is just the analysis of electrical fields by charged particles on each other sufficient or is there a lot more to it?

A proton moves in a circular orbit perpendicular to a uniform magnetic field of 0.758T. Find the time it takes the proton to make one pass around the orbit. Just need someone to help me start off. All I have is that the B=0.758T, q=1.6x10^-19C and m=1.67x10^-27kg. What formulas do I need...

A particle is uncharged and is thrown vertically upward from ground level with a speed of 25.0 m/s. As a result, it attains a maximum height h. The particle is then given a positive charge +q and reaches the same maximum height h when thrown vertically upward with a speed of 30.0 m/s. The...

1. A charged particle was accelerated from rest by a potential difference of 2.50 x 10^5 V. If the particle reached a maximum speed of 2.90 x 10^4 m/s, what potential difference would be required to accelerate this particle from rest to a velocity of 7.25 x 10^4 m/s? 2. The centers of two...

Suppose that a charged particle of diameter 1.00 micrometer moves with constant speed in an electric field of magnitude 1 x 10^5 Newtons per coulomb while acted upon by a drag force of 7.24 x 10^-11 Newtons. What is the charge q1 on the particle? Ignore the effects of gravity. Express your...

When it is said, that 1 coulomb is the amount of electric charge carried by a current of one Ampere for 1 second, and that 1 coulomb is 6.24e18 times the charge of an electron, does it mean that 1 coulomb is 6.24e18 electrons? what is the electrically charged particle that consists of 1 coulomb...

Important! Charged Particle Collisions If two charged particles of equal mass and equal charge start from rest, repel, and travel in opposite directions, in what way is this an accelerating (non-inertial frame of reference)?

If the velocity is in the i direction (v=vi) and the magnetic field is in the -k direction (B=-kB), prove using Newtons Second Law that the trajectory of this charge must be circular? Please help this is really important.

How is the force that a photon exerts on a charged particle calculated?

Hi, a charged particle moves across a constant magnetic field. the magnetic force on this particle? What would you agree on? a) changes the particles speed b) causes the particle to accelerate c) is in the direction of the particles motion or both a & b. I chose C but my test was marked...
