Question

v) Nuclear radius R has a dependence on the
mass number (A) as R=1.3x10-¹⁶ A⅓m.
For a nucleus of mass number A=125,
obtain the order of magnitude of R
expressed in metre.
[Ans: -15]​

Answer 1

Answer:

-15

Explanation:

R=1.3*10-16A1/3m. 1.3*10-16A(125)1/3m

1.3*5*10-16m

6.5*10-16m

65*10-15
