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.
What ray does not affect the photographic plate?
Gamma rays do not affect the photographic plate as they are highly penetrating and pass through without creating an image.
How j.j Thomson discovered electrons are negative?
J.J. Thomson discovered electrons are negative by conducting experiments with cathode rays in vacuum tubes. He observed how the rays were attracted to a positively charged plate, leading him to conclude that the particles in the rays carried a negative charge, which he named electrons.
What is meant by charged metallic plate?
A charged metallic plate is a thin rectangular (or square) sheet that carries a surface charge. Because metal is a conductor, you can assume that the surface charge is spread uniformly over the area of the plate.
What is the charge of these bits of paper on a wooden paper?
The paper bits would be neutral in charge. If the wooden plate has been rubbed against another material, it could acquire an opposite charge, potentially leading to the paper bits being attracted or repelled by the wooden plate.
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 was J J Thompson's hypothesis when he observed that rays bend toward a positively charged plate and give a negative charge to objects they strike?
He hypothesized that cathode rays are streams of electrons or negative charges
What is meaning of perforated cathode?
The. Cathode plate consists of small holes known as perforated cathode plate
What is the electrical charge on the plate that causes the beam to bend toward that plate?
The electrical charge on the plate that causes the beam to bend toward it is negative. This negative charge creates an electric field that interacts with the positively charged ions in the beam, causing them to be attracted towards the negatively charged plate.
How does a cathode ray works?
A cathode ray tube is in the monitor. A hot filament at the rear end of the tube releases electrons. They are negatively charged particles. They are drawn toward a plate which has a positive charge. As they fly toward the plate, electro magnets turn on and off real fast and alter their paths. When they hit the screen, they land on a little dot of a particular color. You see a number of these dots lit up. They combine inside your eye to produce the picture. After the electron hits the screen, it falls down to the positively charged plate.
Why are cathode rays deflected away from a negatively charged plate?
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.
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 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.
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.
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.
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.
