Why are alpha and beta rays deflected in opposite directions in a magnetic field?

An alpha particle, which is a 24He nucleus, has a mass of 4 and a charge of +2. A beta particle has a charge of +1 or -1, depending on whether it is a positron (beta +) or an electron (beta -). It's mass is minuscule compared to the alpha particle, and it will undergo a comparatively huge deflection in the same field as an alpha particle would. Though the alpha particle has twice the charge as a beta particle, it has several thousand times the mass of that beta particle. As it is so much more massive than the beta particle, its inertia will be much more difficult to overcome even though it has twice the charge.

∙ 14y agoBeta particles are much, much lighter than alpha particles, so they deflect much easier.
Alpha particles have more charges (2 positive) than beta particles (1 negative). So, the force on them in a magnetic field should be twice that on the beta particles. However, the mass of the alpha particle is tremendously high (4 nucleons) compared to the beta particle (1 electron). Net effect of this is the acceleration on the beta particle is very high compared to that on the alpha particle. So, beta particles will get deflected more than the alpha particle, even though they would experience more force of deflection.

∙ 12y agoAlpha particles have positive charge and beta particles, at least the most common kind, beta- particles, have negative charge. That is why they deflect in opposite directions from a magnetic field. Gamma rays, on the other hand, are based on photons, which are uncharged, so they do not interact with magnetic fields.

Is gamma radiation effected by a magnetic field?
Nothing. The gamma ray is not deflected by a magnetic field, which demonstrates that unlike the alpha and beta rays, the gamma is not a stream of charged particles, but is electromagnetic radiation.
Why is an alpha particle attracted to a negative plate?
Alpha particles are deflected towards negative plates because they are positively charged.
Why are alpha and beta rays bent in different directions?
Alpha and beta rays are bent in different directions because alpha is positively charged, beta is negative.
What two types of radiation would be deflected by an electric field?
Ionizing radiation is generally divided into electromagnetic radiation and particulate radiation. Charged particles are affected, and this will include protons, beta particles and alpha particles. Neutrons, another particulate form of ionizing radiation, won't be affected. Electromagnetic ionizing radiation, cosmic rays and gamma rays, are not effected.
When a beam of alpha particles passes between two electrically charged plates which plate is the beam deflected toward?
true
Why beta and alpha particles deflected when they pass the magnetic field?
Alpha and beta particles are deflected by a magnetic field because they have charge and, as such, are affected by the electromagnetic interaction or force.
Why were few alpha particles deflected?
some of alpha particles were deflected through an angle of 90 degree
Is gamma radiation effected by a magnetic field?
Nothing. The gamma ray is not deflected by a magnetic field, which demonstrates that unlike the alpha and beta rays, the gamma is not a stream of charged particles, but is electromagnetic radiation.
What did Rutherford call the region that deflected the alpha particles?
Nucleus.
How does Alpha particles affects us?
They don't, or at least, the effect is negligible. Alpha particles can be deflected with a sheet of paper.
Why alpha particles is a threat to humans?
Alpha particles ARE not a threat to humans. They can be deflected by nothing more than a sheet of paper.
When a beam of alpha particles passes between two electrically charged plates - which plate is the beam deflected toward?
The beam would be deflected to the negative plate, as alpha particles are Helium nuclei and are positively charged.
What is the opposite of the alpha male?
The opposite of an Alpha is an Omega. The counterpart to an Alpha male would of course be an Alpha Female.
How Geiger and marsden experiment of alpha was deflected?

Why is an alpha particle attracted to a negative plate?
Alpha particles are deflected towards negative plates because they are positively charged.
Why are alpha and beta rays bent in different directions?
Alpha and beta rays are bent in different directions because alpha is positively charged, beta is negative.
What are the mayor differences between alpha particles and gamma radiation?
Alpha particle is the nucleus of helium atom. That is doubly ionized one. Hence alpha particle is massive and so its velocity is comparatively low. As it is massive it has good ionization power but penetration would become difficult. Isn't? Because it is helium nucleus, it has two positive charges. So can be deflected by electric and magnetic field. But gamma radiation is photons whose rest mass is zero. It is charge less. So cannot be deflected by electric and magnetic field. Its velocity is the highest in the universe ie the velocity of light. It has good penetrating power but least ionizing power.
