Properties of NUclear force

(i) What characteristic property of nuclear force explains the constancy of binding energy per nucleon (BE//A) in the range of mass number 'A' lying 30 lt A lt 170 ? (ii) Show that the density of nucleus over a wide range of nuclei is constant-independent of mass number A.

Give two properties of lines of force.

Which of the following is/are characteristics of nuclear forces?

The nuclear force

Draw a plot of the binding energy per nucleon as a function of mass number for a large number of nuclei , 2 le A le 240 . How do you explain the constancy of binding energy per nucleon in the range 30 lt A lt 170 using the property that nuclear force is short-ranged ?

Identify the correct statement // statements a) At greater distances nuclear forces are negligible b) Nuclear forces are non central forces c) Nuclear forces are weakest in nature d)Nuclear forces are charge dependent forces
