An alpha nucleus of energy 
bombards a heavy of closet approach for the alpha nucleus will be proportional to
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
B
At distance of closest approach relative velocity of two particles is 
. Here target is considered as stationary, so 
-particle comes to rest instantaneously at distance of closest approach. Let required distance is 
, then from work energy-theorem.
