Physics_Student said:For an electron, what is its velocity after it has been accelerated through 50V?
I thought about equating 50eV to KE, but I know that's the wrong way, any ideas?
I don't think that's needed here; the electron's rest mass is about 0.5MeV and we're talking a KE of 50eV.dont forget to calculate that using relativistic Kinetic Energy
An electron is a subatomic particle that carries a negative charge and orbits around the nucleus of an atom. It is one of the fundamental particles that make up all matter.
The charge of an electron is -1. This means that it has one unit of negative charge.
Electrons can move in two ways: through orbiting around the nucleus of an atom, or through free movement in a conductor. The movement of electrons is influenced by electric and magnetic fields.
No, an electron cannot be destroyed. According to the law of conservation of energy, energy can neither be created nor destroyed. Electrons can only be transferred or converted into other forms of energy.
Electrons are used in a wide range of technologies, including electronics, telecommunications, and medical imaging. They are also utilized in scientific research, such as in particle accelerators to study subatomic particles and in electron microscopes to view tiny structures.
