Question

The radius of nucleus of

Al will be
(1) 12*
10-15 m (2) 2.7x10-15 m
(3) 10.8x10-15m
(4) 4x10-15 m​

Answer 1

Answer:

the answer of above question is 2

Answer 2

Answer:

4)4×10-15m

Explanation:

As per formula for finding radius of a nucleus

R=Ro(A)1/3

Ro=constant=1.2×10^-15

A=atomic mass of al=27

So, substituting the values in the given formula

R=Ro(A)1/3

=1.2×10^-15 (27)1/3

=1.2×10^-15×3

=3.6×10^-15

This is the actual answer, but as it isn't given in the options so we will choose the closest value

i.e 4×10^--15.
