Question

Verify the claim that, in terms of gigaelectronvolts, the mass of an mass of an electron is 0.000511

Answer 1

Gigaelectron-volts is a unit of measurement of energy, the abbreviation of gigaelectron-volts is Gev . Thank you for posting your question here. Below is the solution:
0.5109989 MeV=mass of electron in (million electron volts)0.5109989/1000=.0005109989 GeV (Giga=billion electron volts)Hope it helps.
