Question

For the van der Waals interaction with potential-energy function given by the equation U=Uo[(Ro/r)^12 -2(Ro/r)^6], show that when the magnitude of the displacement x from equilibrium (r=Ro) is small, the potential energy can be written approximately as U=1/2kx^2-Uo . (Hint: Let r=Ro+x and u=x/Ro. Then approximate (1+u)^n by 1+nu+ n(n-1)/2! *u^2 .) Essay answers are limited to about 500 words (3800 characters maximum, including spaces). Please HELP. WILL RATE!
