sis my qn is how did they get the MeV as 1.6x10^-13????

ohh didn't see that lulz

anyways looking at the data sheet above e is elementary charge in MeV and M is mega and V is voltage (e and V will cancel [homogeniouty] to give kgm^2s^-2 which is energy)
so 1.1MeV is actually 1.1 * 10^6 * 1.6*10^-19= 1.76*10^-13

0.5*4*1.67*10^-27 * v^2= 1.76*10^-13

hope it helped
