If radius of the `_(13)^(27) Al` necleus is estimated to be `3.6` fermi then the radius of `_(52)^(125)Te` nucleus be nearly

Options

A. 4 Fermi
B. 5 Fermi
C. 6 Fermi
D. 8 Fermi

Answer

C

Explanation

( c) `r prop A^(1//3) rArr (r_1)/(r_2) = ((A_1)/(A_2))^(1//3)`
`rArr (3.6)/(r_2) = ((27)/(125))^(1//3) = (3)/(5) rArr r_2 = 6 Fermi`.
