Find Beta and Gamma for an electron that has a kinetic energy of 6.00 keV.
gamma = KE/MoC^2 + 1
Beta = 1/gamma^2 + 1
gamma = 1.011723381
Beta = 1.9769592
I am getting gamma right but I am getting Beta wrong what I'm I doing wrong??

physics please help 
drwls,
You are using an incorrect equation for beta.
Beta = v/c, which cannot exceed 1.
Beta^2 = 1  (1/gamma)^2
