Answer to Question #124805 in Atomic and Nuclear Physics for pee

Question

If the kinetic energy of an electron in the ground state hydrogen atom is 2.2 x 10-18 J, calculate its momentum

Answer 1

The relationship between the momentum and kinetic energy of an electron is

$p=\sqrt{(2mK)}=\sqrt{(2(9.11*10^{-31})(2.2*10^{-18 }))}$

$=2.00*10^{-24} kg.m/s$
