For a nucleus of mass number 
and radius 
, the mass density of nucleus can be represented as
A
B
Independent of A
C
D
Text Solution
Verified by ExpertsThe correct answer is:
B
The radius 
of a nucleus is given by the empirical relation:
where 
is a constant and 
is the mass number.
The volume 
of the nucleus is approximately that of a sphere:
Substituting the expression for 
into the volume formula:
The mass density 
is defined as the mass
(which is proportional to 
) divided by the volume:
Notice that 
cancels out in the numerator and denominator, so the density is:
meaning it is independent of the mass number A.
