Dear student

U=U0(1-cosax)

Force=-dU/dx=-aU0sinax=-w^2 (x)

from here you can easliy calculate frequency on comparing the two..

U = U0(1-cosax)

F = -dU/dx = -Uoasinax

for small x , sinax is small or sinax = ax

F = -U0a2x

a = -Uoa2x/m                              (a = -w2x)

-w2x = -Uoa2x/m

 w = (Uoa2/m)1/2
