there is a question about a proton with energy of 26GeV and meets a proton at rest. and I am supposed to find the number of proton-antiproton pair are created?(adsbygoogle = window.adsbygoogle || []).push({});

the solution is given by :

E_{a}= square root of ( 2mc^{2}*E_{m})

2Nmc^{2}= square root of ( 2mc^{2}*E_{m})

where E_{a}is the total energy

I dont get how the first formula became like this!
