Atoms And Nuclei Question 208

Question: The mass equivalent of 931 MeV energy is [MP PET 1994; MH CET 2003]

Options:

A) $1.66 \times 10^{- 27} k g$

B) $6.02 \times 10^{- 24} k g$

C) $1.66 \times 10^{- 20} k g$

D) $6.02 \times 10^{- 27} k g$

Show Answer

Answer:

Correct Answer: A

Solution:

$m = \frac{E}{c^{2}} = \frac{931 \times 1.6 \times 10^{- 13}}{{(3 \times 10^{8})}^{2}} = 1.66 \times 10^{- 27} k g .$
