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.


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.


Who explained the behavior of positively charged particles being deflected from a metal foils as the nucleus?

Ernest Rutherford explained the behavior of positively charged particles being deflected from metal foils as they interacted with the nucleus of the atom in his famous gold foil experiment. This experiment led to the discovery of the atomic nucleus as a small, dense, positively charged center within the atom.


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.


What happened to the beam when Thomson placed a pair of charged metal plates on either side of the glass tube?

When J.J. Thomson placed a pair of charged metal plates on either side of the glass tube, the cathode ray beam (consisting of electrons) was deflected. The negatively charged electrons were repelled by the negatively charged plate and attracted towards the positively charged plate, causing the beam to bend towards the positive plate. This experiment demonstrated that cathode rays were made up of negatively charged particles, leading to the discovery of the electron.

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

The beam would be deflected to the negative plate, as alpha particles are Helium nuclei and are positively charged.


Who discovered the nucleus using his gold foil?

Rutherford by bombarding gold foil with positively charged particles and noting that some particles were widely 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.


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 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.


Who discovered the nucleus using his gold foil experiment?

Ernest Rutherford is the scientist who discovered the nucleus through his gold foil experiment in 1909. He observed that most of the alpha particles passed through the foil, but some were deflected, leading him to propose the existence of a dense, positively charged nucleus at the center of an atom.

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 J.J. Thomson discover negative charges?

J.J. Thomson discovered negative charges by studying cathode rays in a vacuum tube, where he observed that they were deflected by electric and magnetic fields in a way consistent with negatively charged particles. This led him to propose the existence of negatively charged particles, which he later named electrons.


Which way will negatively charged particle be deflected by a magnetic field?

A negatively charged particle will be deflected in a direction perpendicular to both its velocity and the magnetic field when moving through the field. This is due to the Lorentz force, which acts on the particle in a direction perpendicular to both its velocity and the magnetic field lines.
