How to convert volts into electrovolts?
What's the mass of an electron?
The formula is v = √(2eV/m), where v is the speed of the electron, e is the charge of an electron, V is the potential difference, and m is the mass of the electron.
The formula is derived from the conservation of energy and the equation for kinetic energy (K = ½mv²). By equating the potential energy gained by the electron across the potential difference to its kinetic energy, we can solve for v.
Yes, this formula can be applied to any charged particle as long as its mass and charge are known. However, it is most commonly used for electrons due to their small mass and charge.
The units for v will be meters per second (m/s), e will be coulombs (C), V will be volts (V), and m will be kilograms (kg).
Yes, this formula is commonly used in various fields such as physics, chemistry, and engineering to calculate the speed of charged particles in different experimental setups, such as particle accelerators and electron microscopes.
