NEET Physics Nuclei Questions Solved

NEET - 2008

Two nuclei have their mass numbers in the ratio of 1:3. The ratio of their nuclear densities would be 

(a) 1:3

(b) 3:1

(c) 31/3:1

(d) 1:1

Density of nuclear matter is indepent of mass number, so the required ratio is 1:1.

Alternative:

                  A1:A2=1:3

Their radii will be in the ratio 

             R0A11/3:R0A21/3=1:31/3Density= A43πR3 P A1 : P A2=143πR03.13=343πR0331/33

Their nuclear densities will be the same .
