1.

from 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 ).

Answer»

SOLUTION :Nuclear MATTER density =`("Mass of nucleus")/("Volume of nucleus")`
`=(mA)/(4/3piR^3) =(mA)/(4/3 piR_0^3A)`
`=m/(4/3piR_0^3)=2.3 xx 10^(17) kg //m^3`
= constant
