form the relation R=R_0A^(1//3) , where R_0 is a constant and A is the mass number of a nucleus, show that the nuclear matter density is nearly constant (i.e., independent of A ).
In both beta^(-1) and beta^(+) decay processes, the mass number of a nucleus remains same, whereas the atomic number Z increases by one in beta^(-) decay and decreases by one in beta^(+) decay. Explain by giving reason.
Consider the following statements (A) and (B) and identify the correct answer given below. Statement (A): Positive values of packing fraction implies a large value of binding energy. Statement (B): The difference between the mass of the nucleus and the mass number of the nucleus is called packing fraction
The radius of a spherical nucleus as measured by electron scattering is 3.6 fm. What is the mass number of the nucleus most likely to be ?
Assertion Positive value of packing fraction implies a large value of binding energy. Reason The ratio of the difference between the atomic mass of nucleus and the mass number of the nucleus to that of atomic mass is called packing fraction.
The radius of a nucleus is given by r_(0) A^(1//3) where r_(0) = 1.3xx 10^(-15) m and A is the mass number of the nucleus, the Lead nucleus has A = 206. the electrostatic force between two protons in this nucleus is approximately
