Question 43

A nucleus of mass number MMM has a nuclear radius RAR_ARA​. Another nucleus has a nuclear radius RBR_BRB​.

Which of the following expressions represents the mass number of this second nucleus?

A

M(RARB)3M \left(\frac{R_A}{R_B}\right)^3M(RB​RA​​)3

B

M(RBRA)3M \left(\frac{R_B}{R_A}\right)^3M(RA​RB​​)3

C

M(RARB)13M \left(\frac{R_A}{R_B}\right)^{\frac{1}{3}}M(RB​RA​​)31​

D

M(RBRA)13M \left(\frac{R_B}{R_A}\right)^{\frac{1}{3}}M(RA​RB​​)31​
