Assertion Positive value of packing fraction implies a large value of binding energy.
Reason The ratio of the difference between the atomic mass of nucleus and the mass number of the nucleus to that of atomic mass is called packing fraction.

A

If both Assertion and Reason are true and Reason is the correct explanation of Assertion.

B

If both Assertion and Reason are true but Reason are true but Reason is not correct explanation of Assertion.

C

If Assertion is true but Reason is false.

D

If Assertion is false but Reason is true.

Text Solution

Verified by Experts

The correct Answer is:
D
(d) Mass defect per nucleon in called is called the packing fraction
`i.e., p=(Deltam)/(A)=(m~A)/(A)`
positive value of P does not mean that `Delta ` m is large , since binding energy E=(Delta )c^(2)`
