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.
How did thomas discover the electron?
J. J. Thomson discovered the electron using an experiment involving cathode rays and a magnetic field. When subjected to the magnetic field, the cathode ray was deflected. If the magnetic field was flipped, the cathode ray was deflected in the opposite direction. This proved that a cathode ray was a stream of negatively charged particles that would later be deemed electrons.
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.
How did JJ Thompson demonstrate the existence of the electron?
JJ Thomson demonstrated the existence of the electron through his cathode ray tube experiment. By observing the behavior of cathode rays in an evacuated tube, he was able to show that these rays were composed of negatively charged particles (electrons) that were much smaller than an atom. This discovery led to the development of the plum pudding model of the atom.
How are cathode charged?
negatively charged
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.
How did JJ Thomson know that the particles in the cathode-ray tube were negatively charged?
They are found to be deflected by electric and magnetic field in the specific direction in which a negatively charged particle would get deflected.
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.
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.
How did Thomson determine that cathode rays are negatively charged?
Thomson observed that cathode rays were deflected by electric and magnetic fields in a manner consistent with them having a negative charge. He measured the charge-to-mass ratio of cathode rays and found it to be the same regardless of the material used for the electrodes, which suggested the charge was a fundamental property of the particles themselves.

How magnetic field is related with cathode rays in physics?
Cathode rays are negatively charged particles that move in curved paths in the presence of a magnetic field. The direction and curvature of the cathode rays can be controlled by adjusting the strength and orientation of the magnetic field. This phenomenon is known as the magnetic deflection of cathode rays and is used in devices like cathode ray tubes.

This discovery led to the development of the plum pudding model of the atom.
Why cathode rays are negatively charged?
Cathode rays are negatively charged because they are composed of electrons, which have a negative charge. When a high voltage is applied to the cathode in a vacuum tube, electrons are emitted from the cathode and accelerated towards the anode, creating a beam of negatively charged particles known as cathode rays.
How are cathode charged?
negatively charged
What would happen to cathode rays in a vacuum?
Cathode rays in a vacuum would travel until stopped (or deflected by an electromagnetic field).
