Question

Mass equivalent to energy 931 MeV is

• A. $6.02\times {10}^{-27}kg$
• B. $1.66\times {10}^{-27}kg$
• C. $16.66\times {10}^{-27}kg$
• D. $6.02\times {10}^{-27}kg$

Answer 1

Answer: (B)

According to Einsteins mass energy equivalence relation $m=\frac{E}{c^2}=\frac{931\times 1.6\times {10}^{-13}}{{(3\times {10}^8)}^2}$ $=1.66\times {10}^{-27}kg$
