A) \[{{10}^{6}}\]sec
B) \[{{10}^{8}}\]sec
C) \[{{10}^{12}}\]sec
D) \[{{10}^{16}}\]sec
Correct Answer: C
Solution :
Mass defect =\[RV\propto n\] \[=0.026\ amu=0.026\times 931\times {{10}^{6}}\times 1.6\times {{10}^{-19}}J\] \[=3.82\times {{10}^{-12}}J\] Power of star =1016W Number of deuterons used \[=\frac{{{10}^{16}}}{\Delta M}=0.26\times {{10}^{28}}\] Deuteron supply exhausts in\[\frac{{{10}^{40}}}{0.26\times {{10}^{28}}}={{10}^{12}}s\].You need to login to perform this action.
