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.
Why cathode ray bent toward the possitively charge plate?
electrons are not bent, they can't be as they are point particles occupying no volume. they are attracted to positive charges. the electron beam (aka cathode rays) are bent toward the positively charged plate.
What type of charge do alpha particles have?
The alpha particle is the nucleus of a helium atom and hence has 2 protons and 2 neutrons. The neutron is neutral and the proton has a +1 elementary charge. The alpha particle therefore has an elementary charge of +2
What is fizeau fringes?
it is interference produced from light entering an inclined plate , it is used to measure small distances, the distance can be measured using the equation: (delta) x= lambda/2 alpha Alpha is the angle between the inclined plate and the horizontal surface, x is the distance from the point of contact to the spacer inclining the plate, y is the distance being measured.
When a beam of alpha particles passes between two electrically charged plates which plate is the beam deflected toward?
true
Why are cathode rays deflected away from a negatively charged plate?
Alpha Rays are attracted to a negatively charged plate because they consist of positively charged particles.
What evidence did Thompson have that his glowing beam contained negative particles?
The beam was repelled by the negative charged plate and attracted by the positively charged plate

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.
Would an electron move toward the positive plate or negative plate?
First of all this isn't a question about Plate Tectonics . Plate tectonics is the behavior of the big geographical areas in which the world is divided in, known as plates. But, answering your question, an election is a negative charge and thus will be attracted to the positive plate.
Is alpha plate silver plate?
alpha plate is modern electroplate, not to confuse with sheffield plate. the name sheffield should only refer to location marc
When placed between oppositely charged metal plates the region of a water molecule that is attracted to the negative plate is the .?
partially positively charged hydrogen end of the molecule.
In thomson's experiment why was the glowing beam repelled by a negatively charged plate?
The experiment showed the relation of positive/negative charges. The beam was made of positively charged ions, which were repelled. -there is another answer to this question that says " because it was attracted to the positive charged plate" this is FALSE, this is just a person trying to make a smart remark. --------- Cathode rays are a beam of electrons; electrons are elementary particles with a negative electrical charge.
Are cathode rays deflected toward a negatively charged plate in an electric field?
Yes. Cathode rays, otherwise known as electrons, are repelled by a negative charge, and attracted to a positive charge.
Why mass spectroscopy only measure positive ion?
It's because negatively charged ions would not be attracted to the negative plate so it's not accelerated and thus it would not reach the detector.
Are protons attracted to a negatively charged metallic plate?
yes they are.
Is alpha plate real silver?
i have a 925 silver bracelet that is italian
