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.
The cathode "ray' must have been made up of negatively charged particles, now called electrons.
As an electron is brought closer to a negatively charged plate, its potential energy increases. Since like charges repel, the electron has to be "brought" near the negatively charged plate ... it'll never go there on its own. You have to push it there, meaning you have to do work on it, and that work adds to the potential energy of the electron. As soon as you let it go, it'll whizz AWAY from the negatively charged plate, and that energy you put into it will turn into the kinetic energy of a hasty retreat.
The metallic coil is embedded in a ceramic plate, heating it up, from this ceramic material the heat is distributed to the surrounding area.
Alpha particles are deflected towards negative plates because they are positively charged.
electrons are not bent, they can't be as they are point particles occupying no volume. they are attracted to positive charges. the electron beam (aka cathode rays) are bent toward the positively charged plate.
yes they are.
proton
They neutralize.
Metallic bonding is the attraction between positively charged metal ions and free (negatively charged) electrons.
Metallic Bond .
touch it with a charged object....
atoms in metallic bonds are positively charged due to stable configuration as the extra electrons are either donated to another atom or atom completes it last shell by receiving electrons which makes it positively charged.
FOR tESTING THE SIGN OF CHARGE ON BODY, a device called GOLD LEAF ELECTROSCOPE. When the disc of a positively charged is touched with any plate of the charge capacitor. IF the divergence of gold leaf increases, then the plate is positively charged and if the divergence in the leaf decrease then the plate of the capacitor is nagatively charged.
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.
The beam was repelled by the negative charged plate and attracted by the positively charged plate
sphere
Whichever plate is connected to the positive end of a battery.
