What experiment did j.j Thomson do?
J.J. Thomson is best known for his experiment with cathode rays, where he deduced the existence of negatively charged particles (electrons) in atoms. By measuring the deflection of these rays in a magnetic field, Thomson was able to determine the charge-to-mass ratio of the electron.
What experiment do Thomson do?
He hit plates with light
What happens to a charged particle placed between two charged plates?
When a charged particle is placed between two charged plates, it will experience a force due to the electric field created by the plates. The particle will move in the direction of the force, either towards the positively charged plate or the negatively charged plate, depending on the charge of the particle and the plates.
How are two parallel plates charged with electricity and what effect does this have on the electric field between them?
When two parallel plates are charged with electricity, one plate is positively charged and the other is negatively charged. This creates an electric field between the plates, with the positive charges attracting negative charges and vice versa. The electric field between the plates becomes stronger as the magnitude of the charges on the plates increases.
When a beam of alpha particles passes between two electrically charged plates which plate is the beam deflected toward?
The beam of alpha particles is deflected toward the negatively charged plate. This is because alpha particles are positively charged, and opposite charges attract each other.
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.

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 happened to the beam when Thompson placed a pair of charged metal plates on either side of the glass tube?
When Thompson placed the charged metal plates on either side of the glass tube, the beam of electrons was deflected towards the positive side of the tube. This demonstrated that the electrons were negatively charged and attracted towards the positive plate, suggesting the presence of negatively charged particles within the atom.
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
