Obtain approximately the ratio of nuclear radii of `._26U^(56)` and `._92U^(238)`. What is the approximately ratio of their nuclear densities?
Text Solution
Verified by Experts
Here, `A_1=56, A_2=238` `(R_1)/(R_2)=((A_1)/(A_2))^(1//3)=(56/238)^(1//3)=(0.235)^(1//3)=0.617` As nuclear density is same for all nuclei, therefore, `(rho_1)/(rho_2)=1`
