Calculate the kinetic energies of protons whose momenta are 0.10,1.0. and 10GeV//c, where c is the velocity of light.

Answer»

Solution :The formula is `T=sqrt(C^(2)p^(2)+m_(0)^(2)c^(4))-m_(0)c^(2)`
THUS `T= 5.3MeV fo R p= 0.01(GeV)/(c )= 5.3xx10^(-3)GeV`
`T= 0.433GeV fo r p=1.0(GeV)/(c )`
`T=9.106GeV for p=10(GeV)/(c )`
Here we have used `m_(0)c^(2)= 0.938GeV`
