A star initially has 
deuterons. It produces energy via the processes 
and 
, where the masses of the nuclei are 
amu, 
amu, 
amu and 
amu. If the average power radiated by the star is 
, then the deuteron supply of the star is exhausted in a time of the order of
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
C
Net process is, 
Mass defect, 
Energy released by the fusion of three deuterons
∴ Total energy released 
Total time 
The order of time is 
.
