the atomic masses of two different nuclei are 3 and 81 then the ratio of their radius r

Asked by akashjyani705 | 6th Mar, 2022, 04:39: PM

Expert Answer:

Radius R of nucleus is given as
 
R = Ro A1/3
 
where Ro = 1.2 × 10-15 m    and A is mass number of nucleus
 
for nuclear mass no. 3 , R = 1.2 × 10-15 × 31/3 = 1.731 × 10-15 m
 
for nuclear mass no. 81 , R = 1.2 × 10-15 × 811/3 = 5.192 × 10-15 m
