Given below are two statements : one is labelled as Assertion A and the other is labelled as Reason R
Assertion A : The binding energy per nucleon is practically independent of the atomic number for nuclei of mass number in the range 30 to 170.
Reason R : Nuclear force is short ranged.
In the light of the above statements, choose the correct answer from the options given below
Both A and R are true but R is NOT the correct explanation of A
Both A and R are true and R is the correct explanation of A
A is true but R is false
A is false but R is true
Ebn is nearly constant in the range 30 < A < 170 because the nuclear force is short-ranged.
