What effect will a positively charged metal plate have on a cathode ray?
Wiki User
∙ 14y ago
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.

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
When cathode rays strike a metal target say tungsten what happens?
x-rays are emitted
What is the importance of DC current flow instead of AC during electroplating process?
Electroplating involves moving metal from one electrode to another, through a conductive solution. Typically a metal at the anode will lose an electron, become dissolved in solution, and then move in the solution towards the cathode. Once reaching the cathode, the metal ion gains electron(s) and is thus deposited at the cathode. With AC, the metal ions would just move back and forth in the solution, generating heat but no electroplating.
What is the filament used in tubelight-?
The type of filament used in tube light is that one which is thin and surrounded by an oblong metal shield.
Electroplating is the process of depositing a thin layer of metal onto another by means of?
A solution of ions of the metal to be plated in an ionizing solvent. Electroplating occurs on the cathode imposed by an external electromotive force.
In electrolysis move between two metal strips called?
Electrodes, the positive side is called the Cathode and the Negative side is called the Anode.The anode and cathode. The anode is positively charged and the cathode is negative.
In electrolysis electrons move between two metal strips called?
Electrodes, the positive side is called the Cathode and the Negative side is called the Anode.The anode and cathode. The anode is positively charged and the cathode is negative.

Why cathode rays are negatively charged?
Cathode rays are produced when the metal cathode has a high voltage applied to it - this has the effect of "boiling" the electrons off the cathode's surface producing cathode rays, and so cathode rays can be seen as a stream of electrons i.e. negatively charged particles.AnswerElectrons are released from the surface of a cathode through thermionic emission. This is achieved by a heaterlocated at the cathode, and not due to a high voltage. The function of the high voltage (between the cathode and an anode placed closer to the screen) is to attract these electrons towards the screen of the CRT. So a 'cathode ray' is simply a beam of electrons which, of course, are negatively charged.
What is the attraction between positively charged metal ions and the electons in a metal?
metallic bond
What type of ion is formed by metal atom?
Cations, positively charged
What force of attraction between a positively charged metal ion and the electrons in a metal called?
The Force
What is the force of attraction between positively charged metal ion and the electron in a metal?
electrostatic force
How do you recognize the difference between the ion charge of a metal and the non metal?
Metal ions are typically positively charged, while nonmetals are typically negatively charged.
Is magnesium metal positively charged?
No, as a metal magnesium is neutral. When it forms compounds it forms positive ions.
What is a bond formed by the attraction between positively-charged metal ions and the electrons in the metal?
it is a metallic bond.
What experiment did J Thomson do?
He sent a cathode ray between electrically charged metal plates.
