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.
