Part a is done,please do part b

2. (a) Sketch the graph of potential energy E(r) versus interatomic separation / when two Si atoms are brought together from infinity. Show the numerical values of the bond length ro= 0.60 nm and bond energy Eo = 2.85 eV on the plotted graph. (5 marks) (b) In order to reach the equibrium state in part (a), what conditions of force and potential energy should be met? Give the bond type of Si. (5 marks)2 ( a) Yo = 0. 6um, bond energy to = 2.85ev ER ITI - 4 attraction repulsion s+ EA
