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.
Which scientist used a cathode ray tube to discover negatively charged subatomic particles?
The scientist who used a cathode ray tube to discover negatively charged subatomic particles was J.J. Thomson.
A cathode ray produced in a gas-filled tube is deflected by a magnetic field A wire carrying an electric current can be pulled by a magnetic field A cathode ray is deflected away from a negatively?
A cathode ray in a gas-filled tube is deflected by a magnetic field due to the Lorentz force acting on the charged particles in the ray. A wire carrying an electric current can be pulled by a magnetic field through the interaction of the magnetic field and the moving charges in the wire. A cathode ray is deflected away from a negatively charged object due to the repulsion between the negatively charged object and the negatively charged particles in the cathode ray.
The discovery and characterization of cathode rays was important in the development of the atomic theory because?
The discovery and characterization of cathode rays led to the identification of electrons as subatomic particles. This discovery was crucial in the development of the atomic theory as it provided evidence for the existence of negatively charged particles within atoms. It also laid the groundwork for the understanding of atomic structure and the concept of the atom as having a positively charged nucleus surrounded by 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.
What does a cathode ray consists of?
A cathode ray consists of a stream of electrons generated by heating a cathode. These electrons are accelerated and focused by electric and magnetic fields before hitting a phosphorescent screen to produce a visible image.
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.
What is the charge of the cathode tube particles?
Cathode rays are high speed electrons. So they are negatively charged.
Which scientist used a cathode ray tube to discover negatively charged subatomic particles?
The scientist who used a cathode ray tube to discover negatively charged subatomic particles was J.J. Thomson.
Is cathode rays are material particles?
Cathode rays are streams of electrons that travel from the negatively charged cathode to the positively charged anode in a cathode ray tube. They are not material particles in the traditional sense because they do not have mass or volume, but rather behave as electron beams.
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.
Who said Cathode rays are made up of negayively charged particles?
J.J.Thompson
Which scientist discovered that cathode rays are made up of negatively charged particles?
J.J. Thomson discovered that cathode rays are made up of negatively charged particles. He conducted experiments using cathode ray tubes and found that the rays were deflected by electric and magnetic fields in a manner consistent with the presence of negatively charged particles.
What is the nature of charge on cathod rays?
Cathode rays are negatively charged particles, which are typically electrons. These electrons are emitted from the cathode in a vacuum tube and are attracted to the positively charged anode.
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.
3 All nuclear radiation consists of charged particles true or false?
False, neutrons are not charged and gamma rays aren't charged particles.
