AIIMS 2000 Physics Nuclear Density Assertion Reason Question
Type: Assertion Reason-conceptual-Medium-Class 12
Assertion: Density of all the nuclei is same.
Reason: Radius of nucleus is directly proportional to the cube root of mass number.
A
Both A and R are true and R is the correct explanation of A.
B
Both A and R are true but R is not the correct explanation of A.
C
A is true but R is false.
D
A is false but R is true.
Correct Answer
Option A
Detailed Explanation
The density of a nucleus is constant because the volume of a nucleus is proportional to the number of nucleons, and the mass is also proportional to the number of nucleons. Thus, the density remains constant.
