A) \[9\times {{10}^{13}}J\]
B) \[3\times {{10}^{8}}J\]
C) \[3\times {{10}^{15}}J\]
D) \[9\times {{10}^{15}}J\]
Correct Answer: A
Solution :
According to Einstein's theory of relativity, matter is completely converted into energy or vice-versa. The relation is \[E=\Delta m{{c}^{2}}\] Given,\[\Delta m=1\,\,mg=1\times {{10}^{-3}}g,\,\,c=3\times {{10}^{8}}m/s\] \[\therefore \] \[E=1\times {{10}^{-3}}\times {{(3\times {{10}^{8}})}^{2}}\] \[=9\times {{10}^{13}}J\]
