It is found that if a neutron suffers an elastic collinear collision with deuterium at rest, fractional loss of its energy is 
; while for its similar collision with carbon nucleus at rest, fractional loss of energy is 
. The values of 
and 
are respectively:
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
B
Before collision
Neutron Neucleus
After collision
(from conservation of momentum)
and 
(for elastic collision)
So after solving
For Deuterium, 
For Carbon,
