Cathode rays are deflected away from a negatively charged plate because they are negatively charged particles themselves. Like charges repel each other, so the negative cathode rays are pushed away from the negative plate.

In thomson's experiment why was the glowing beam repelled by a negatively charged plate?

In Thomson's experiment, the glowing beam was repelled by a negatively charged plate because the beam consisted of negatively charged particles (electrons). Since like charges repel each other, the electrons in the beam were repelled by the negative charge on the plate.

What is the evidence that show cathode rays consists of charged particles?

One piece of evidence is the observation that cathode rays are deflected by electric and magnetic fields, indicating they carry charge. Further evidence comes from the fact that cathode rays produce X-rays when striking a target, which is consistent with the behavior of charged particles like electrons. Additionally, the ratio of the charge to mass of the particles in cathode rays was found to be the same as that of electrons.

What evidence did Thompson have that his glowing beam contained negative particles?

Thompson's evidence came from observing the deflection of the beam in a magnetic field. By observing the direction of the deflection and comparing it to the known behavior of negatively charged particles, he inferred that the beam contained negatively charged particles.

Why During Electroplating The Article To Be Plated Is Always Made The Cathode?

Placing the article to be plated at the cathode allows for a controlled deposition of metal ions from the electrolyte onto its surface. The high electric field at the cathode attracts the positively charged metal ions, promoting the formation of a uniform and adherent metal coating on the article.

What would the cathode be in a nickel and copper electrolyte cell?

Ni(s)

Are cathode rays deflected toward a negatively charged plate in an electric field?

Yes, cathode rays are deflected towards a positively charged plate in an electric field. The negatively charged particles in the cathode rays are attracted to the positive plate, causing the deflection.

What effect will a positively charged metal plate have on a cathode ray?

Since a cathode ray is a stream of electrons, and since electrons are negatively charged, a positively charged metal plate would cause a deflection in the cathode ray towards the plate.

When Thomson held a positively charged plate near the cathode ray the beam bent toward the plate What conclusion can be drawn from this observation?

The beam bending towards the positively charged plate indicates that the cathode rays are negatively charged. This observation led Thomson to conclude that the cathode rays are made up of negatively charged particles, which we now know as electrons.

When a beam of alpha particles passes between two electrically charged plates - which plate is the beam deflected toward?

The beam of alpha particles will be deflected toward the negatively charged plate. This is because alpha particles are positively charged and are attracted to the negative plate.

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.

Why cathode ray bent toward the possitively charge plate?

Cathode rays are deflected towards a positively charged plate because they are made up of negatively charged electrons. The positively charged plate attracts the negatively charged electrons, causing them to move in that direction. This deflection can be explained by the principles of electrostatic force.

In thompsons experiment why was the glowing beam repelled by a negatively charged plate?

In Thompson's experiment, the glowing beam was repelled by a negatively charged plate because the beam consisted of negatively charged particles known as electrons. Like charges repel each other according to the principles of electrostatics, causing the beam to be deflected away from the negatively charged plate.

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.

In thomson's experiment why was the glowing beam repelled by a negatively charged plate?

In Thomson's experiment, the glowing beam was repelled by a negatively charged plate because the beam consisted of negatively charged particles (electrons). Since like charges repel each other, the electrons in the beam were repelled by the negative charge on the plate.

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

How are cathode rays originated?

its negatively charged particles of matter,Thomson knew that opposites attract but these the positive charged anode,so he reasoned that the paticles must be negatively charged! : )! Wooooo! Go J.J Thomson
