The mass equivalent of 931 MeV energy is.

A

1.66×10−27kg1.66 \times 10^{- 27}kg

B

6.02×10−24kg6.02 \times 10^{- 24}kg

C

1.66×10−20kg1.66 \times 10^{- 20}kg

D

6.02×10−27kg6.02 \times 10^{- 27}kg

Answer

1.66×10−27kg1.66 \times 10^{- 27}kg

Explanation

Solution

m=Ec2=931×1.6×10−13(3×108)2=1.66×10−27kg.m = \frac{E}{c^{2}} = \frac{931 \times 1.6 \times 10^{- 13}}{(3 \times 10^{8})^{2}} = 1.66 \times 10^{- 27}kg.
