Atoms And Nuclei Question 208
Question: The mass equivalent of 931 MeV energy is [MP PET 1994; MH CET 2003]
Options:
A) $ 1.66\times {{10}^{-27}}kg $
B) $ 6.02\times {{10}^{-24}}kg $
C) $ 1.66\times {{10}^{-20}}kg $
D) $ 6.02\times {{10}^{-27}}kg $
Show Answer
Answer:
Correct Answer: A
Solution:
$ m=\frac{E}{c^{2}}=\frac{931\times 1.6\times {{10}^{-13}}}{{{(3\times 10^{8})}^{2}}}=1.66\times {{10}^{-27}}kg. $
