What experiment did j.j Thomson do?
He sent a cathode ray between electrically charged metal plates.
How does an electrostatic air cleaner work?
Electrostatic air cleaners have a "corona discharge", which ionizes the particles in the air, making them either negative or positive. After the particles are charged, they pass over a series of charged plates, which attract the oppositely charged ions, removing the particles of dust, dirt, etc. from the air.
What is the purpose of the grid and X and Y-plates in cathode ray oscilloscope?
X-plates:Controls motion of beam horizontally across the screenY-plates: Controls motion of beam vertically across the screen
What is electric potential in between twooppositely charged plates?
The electric potential difference is measured in volts. The amount of volts will depend on what kind of plates and the solution which the plates have been put in to.
Why is an alpha particle attracted to a negative plate?
Alpha particles are deflected towards negative plates because they are positively charged.
How do charged plates affect the plates of cathode rays?
The electron particles in cathode rays have a negative charge. So if a plate is positively charged, it would attract the cathode rays, and if it was negatively charged, it would repel the rays.
How do charged plates affect the path of cathode rays?
The electron particles in cathode rays have a negative charge. So if a plate is positively charged, it would attract the cathode rays, and if it was negatively charged, it would repel the rays.
How did the cathode ray experiment prove the existence of a negatively charged particle?
They found that the rays bent towards positively charged plates and away from negatively charged plates. Knowing that objects which have like charges repel eachother, they concluded that the rays have a negative charge.
What experiment did j.j Thomson do?
He sent a cathode ray between electrically charged metal plates.
What experiment did J Thomson do?

Why electron does not fall in one of the charged plate of opposite polarity when moving inside electric field?
An electron, being negatively charged, will move towards positively charged plates.
What is the name of the battery positive and negative plates in a typical lead acid battery when the battery is in a charged condition?
anode (negative) cathode (positive) Source: www.bdbatteries.com
How did Thomson know that the electrons that he had discovered had a negative charge?
He devised a crook's tube with a near perfect vaccum with two aluminum plates in the center of the tube. One plate served as the anode to a circuit while the other served as a cathode, effectively creating a magnetic field between then with a negative field on one side and a positve field on the other. electrons (cathode rays) were then passed through, Because electrons are negatively charged, the negatively charged anode will repel them and force them to strike the florescent screen at a lower spot than if allowed to pass through freely. When the current it reversed the electrons strike the screen at a higher point than would normally occur
Name of positive and negative plates of a lead battery?
Anode and cathode
What Thomson's experiment?
This was the discovery of deflection of cathode rays in an electromagnetic field.
Why are the tanks on oil tankers often filled with nitrogen before they are cleaned?
So that the oil in the oil tanker can spontaneously combust with the nitrates in the nitrogen solution that is added causing a neutralisation reaction which then leads to the positively charged dust particles in the smoke that rises after being heated are attracted to the negatively charged metal plates.
What evidence is there that electrons are negatively charged particles?
You should understand that it is an arbitrary choice, to call the charge on an electron negative rather than positive. Everything that we know about electromagnetism and sub-atomic particles would work just as well if we had decided to call the charge on the electron plus one, and the charge on the proton minus one. What matters is that protons and electrons have opposite charges (and of course, the various other charged particles have their various charges which relate to the charges of protons and electrons). That is all that we are trying to convey by the use of the term negative. It is opposite to the proton. The existence of these charges is abundantly, even super-abundantly verified by countless millions of experiments, observations, electrical devices, etc.
