MCQ
$1$ a.m.u. is equivalent to
- A$1.6 \times 10^{-12}$ Joule
- B$1.6 \times 10^{-19}$ Joule
- ✓$1.5 \times 10^{-10}$ Joule
- D$1.5 \times 10^{-19}$ Joule
✓
Answer
Correct option: C.
$1.5 \times 10^{-10}$ Joule
$1 \mathrm{amu}=1.66 \times 10^{-27} \mathrm{~kg}$
$E=mc^2=1.66 \times10^{-27} \times \left(3 \times 10^8\right)^2=1.5 \times 10^{-10} \mathrm{~J}$
$E=mc^2=1.66 \times10^{-27} \times \left(3 \times 10^8\right)^2=1.5 \times 10^{-10} \mathrm{~J}$
