The potential energy of a diatomic molecule is given by U = A/r¹² - B/r⁶ where r is the distance between the atoms that make up the molecule and A,B are positive constants. Find the equilibrium separation betweeen atoms

for equilibrium positions dU/dR= -F must be zero

U=A/r¹²-B/r⁶

dU/dR= -12A/r¹³+6B/r⁷=0

B/r⁷=2A/r¹³

r⁶=2A/B

r=(2A/B)^1/6

Three identical balls are placed on a frictionless horizontal surface touching each other. They stick to each other because of adhesive. Another ball of same radius and mass m is placed over the void created by the three balls. Find the forces applied by the balls kept on the floor to each other if the system remains in equilibrium.
