938 MeV c- 2=m E=mc2=938 MeV=9.38× 108 eV

Q. The rest mass of a proton is $938 M e V c^{- 2}$ . The energy of a proton at rest is,

$9.38 J$

$9.38 \times 1 0^{8} \times 3 \times 1 0^{8^{2}} J$

$9.38 \times 1 0^{8} e V$

$9.38 \times 1 0^{8} \times 3 \times 1 0^{8^{2}} e V$

$938 M e V c^{- 2} = m$
$E = m c^{2} = 938 M e V = 9.38 \times 1 0^{8} e V$

Q. The rest mass of a proton is 938MeVc−2 . The energy of a proton at rest is,
