1.	If the potential energy is minimum at r = ro = 0.74Ao, is the force attractive or repulsive at r = 0.5Ao; 1.9Ao and α?
Answer» Since, potential energy is minimum at r_o = 0.74A^o. therefore interatomic force between two atoms is zero for r_o = 0.74A^o . 1) At r = 0.5 A^o (Which is less than r_o), the force is repulsive. 2) At r = 1.9A^o (Which is greater than r_o), the force is attractive. 3) At r = α, the force is zero.

Answer»

Since, potential energy is minimum at r_o = 0.74A^o. therefore interatomic force between two atoms is zero for r_o = 0.74A^o .

1) At r = 0.5 A^o (Which is less than r_o), the force is repulsive.

2) At r = 1.9A^o (Which is greater than r_o), the force is attractive.

3) At r = α, the force is zero.
