Acertain particle is at rest with respect to you. assuming that you measure its mass to be 1 g, what is its energy? 1 ev = 1.6 x 10^-19 j. answer in units of mev.

5.625×10²⁶ MeV

Explanation:

m = Mass of particle = 1 g = 0.001 kg

c = Speed of light = 3×10⁸ m/s

Einstein's equation

E = mc²

⇒E = 0.001×(3×10⁸)²

⇒E = 9×10¹³ J

1 eV = 1.6×10⁻¹⁹ J

So,

Converting to MeV

1 MeV = 10⁶ eV

So,

The energy of the particle is 5.625×10²⁶ MeV.
