A neutron collides head–on with a stationary hydrogen atom in ground state. Which of the following statement is/are correct? (Take mass of H–atom equal to mass of neutron)
Text Solution
Verified by ExpertsThe correct answer is:
CHECK THE SOLUTION.
(a,c)
mv 0 = mv 1 + mv 2
⇒ v 1 + v 2 = v 0 .... (1)
= 
+ 
+E
= 
+ 
+ 
.... (2)
⇒ v 1 v 2 = 
= 
– 2v 1 v 2 ≥ 0
⇒ 
– 4v 1 v 2 ≥ 0
≥ 2E
E = Minimum Excitation energy
= 10.2 eV
∴ KE initial ≥ 20.4 eV
