On disintegration of one atom of 
, the amount of energy obtained is 200 MeV . The power obtained in a reactor is 1000 kilo watt. What is the decay in mass per hour approximately?
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
C
Power produced in the reactor is
As in each disintegration 200 MeV energy is released, number of atoms disintegrated per second are 
Energy released per second is 
Energy released per hour 
Thus, mass decay per hour can be given as
(Einstein's mass-energy formula)
