State three properties of nuclear forces. Show that the density of nuclear matter is independent of mass number A.

State two characterstics properties of nuclear forces?

What are nuclear pores? State their function.

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).

What characteristic properties of nuclear force explains the constancy of binding energy per nucleon (B.E//A) in the range of mass number A lying 30 ltAlt170 ?
