Experimentally, it is found that the average radius of a nucleus is given by R=R0 A1 / 3 where R 0=1.1 × 10-15 m =1.1 fm and A = mass number

Both Assertion and Reason are true but Reason is not the correct explanation of Assertion

Assertion is true but Reason is false

Assertion is false but Reason is true

Experimentally, it is found that the average radius of a nucleus is given by $R = R_{0} A^{1/3}$ where R _0=1.1 \times 10^{-15} m =1.1 fm and $A =$ mass number
