What is the total energy of a particle with a rest mass of 1 gram moving with half the speed of light? 1 ev = 1.6 x 10^-19 j. answer in units of ev.

6.5 x 10^32 eV

Explanation:

mass of particle, mo = 1 g = 0.001 kg

velocity of particle, v = half of velocity of light = c / 2

c = 3 x 10^8 m/s

Energy associated to the particle

E = γ mo c^2

Convert Joule into eV

1 eV = 1.6 x 10^-19 J

So,
