A) \[9\times {{10}^{-13}}J\]
B) \[9\times {{10}^{-16}}J\]
C) \[9\times 1013\text{ }J\]
D) \[9\times {{10}^{16}}J\]
Correct Answer: C
Solution :
If\[m=1\text{ }amu,\text{ }c=3\times {{10}^{8}}m/s\text{ }then\] \[E=931\text{ }MeV\] 1 amu\[=1.6\times {{10}^{-27}}kg\] \[1.6\times {{10}^{-27}}kg\] is equal to 931 MeV. \[\therefore \]1 kg is equal to\[\frac{931}{1.6\times {{10}^{-27}}}\]MeV \[\therefore \]1 g is equal to\[\frac{931\times {{10}^{-3}}}{1.6\times {{10}^{-27}}}\]MeV \[=5.81\times {{10}^{26}}MeV\] \[5.81\times {{10}^{26}}MeV=5.81\times {{10}^{26}}\times 1.6\times {{10}^{-13}}J\] \[=9.2\times {{10}^{13}}J\]
