Homework Statement
Some electrons are accelerated through a P.d. of 500 V.
[e = 1.6x10^-19 C, mass of electron = 9.1x10^-31 Kg, h = 6.6x10^-34 Js.]
1. What is the kinetic energy of one of the electrons in eV?
2. What is the velocity of one of the electrons?
3. What is the momentum of one of the electrons?
4. What is the wavelength of the electron?
