(a)
State Bohr’s postulate of quantisation of angular momentum.
(b)
Show how it can be obtained from wave nature of orbiting electrons.
(c)
Plot a labelled graph showing variation of binding energy per nucleon of a nucleus versus its mass number.
Draw: graph showing variation of binding energy per nucleon versus mass number
Must show: peak near A=56 (Fe-56), sharp peaks for He-4, C-12, O-16, decrease towards high mass numbers (heavy nuclei)
