What will happen to an electron placed at midpoint between plates?

If I place an electron at a point halfway between the plates, which way will it move? The electric field points in the direction of the force that would be on a positive charge. An electron will move in the opposite direction of the electric field because of its negative charge. Therefore it will move toward the left.

How an electron and a positively charged atom would behave differently when passed through electrically charged plates?

Behavior of protons, neutrons and electrons in electric fields. Protons are positively charged and are thus deflected on a curving path towards the negative plate. Electrons are negatively charged and are deflected on a curving path towards the positive plate.

What happens when electrons are attracted to something with a positive charge?

The electron from one atom will be attracted to the next atom in the direction of the positive charge. The atom will jump out of its orbit in its atom into the orbit of the next atom. This movement of electrons from atom to atom is what we call an electric current.

What happens when positively charged?

In contrast to the attractive force between two objects with opposite charges, two objects that are of like charge will repel each other. That is, a positively charged object will exert a repulsive force upon a second positively charged object. This repulsive force will push the two objects apart.

How an electron behaves in an electric field?

Charged particles move in straight lines and accelerate (or decelerate) if projected into an electric field along the direction of the field. In an electric field the electron moves at a constant velocity at right angles to the field but accelerates along the direction of the field.

How did he know that the nucleus was positively charged?

How did he know that the nucleus was positively charged? He knew the nucleus was positively charged because the positively charged alpha particles were bouncing back rather than becoming stuck to the nucleus.

When a positively charged ion moves in the same direction as the electric field How does the electric potential energy change?

When work is done on a positive test charge to move it from one location to another, potential energy increases and electric potential increases.
