A nucleus at rest splits into two nuclear parts having radii in the ratio 
. Their velocities are in the ratio
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
C
Let 
and 
be the mass numbers of the two nuclear parts. Their radii are given by
and 
Dividing eqn. (i) by eqn. (ii), we get
As 
(given)
Hence the ratio of their masses is
According to law of conservation of linear momentum
magnitude of 
magnitude of 
i.e., 
or 
(using (iii))
