Question

The mass equivalent of 931 MeV energy is
(a) 1.66 ˣ 10⁻²⁷ kg
(b) 6.02 ˣ 10⁻²⁴ kg
(c) 1.66 ˣ 10⁻²⁰ kg
(d) 6.02 ˣ 10⁻²⁷ kg

Answer 1

Energy-Mass Equivalence is defined as:

E=mc2E=mc2

Rearrange to solve for the mass equivalence:

m=Ec2m=Ec2

m=931MeV(3.0×108m/s)2m=931MeV(3.0×108m/s)2

m=1.4916×10−10J(3.0×108m/s)2m=1.4916×10−10J(3.0×108m/s)2

m≈1.657×10−27kgm≈1.657×10−27kg

Therefore, the Mass Equivalence of 931MeV931MeVis approximately 1.657×10−27kg
