I solved at last. a=(c/k)^1/2 and w=(2k/m)^1/2 , w=(V''(a) /m)^1/2. Thanks.

The exam was three days ago. Nobody could solve this question and a similar one (in which F = -kx +a/x^3) The teacher gave us as a homework. If i will solve maybe my exam mark will increase but i am not sure this. Maybe not. If you don not want to help it is up to you. I will study on it again...

w =2π/T T:period. i think you can find w with this equation.

Thanks, you are right. Total force, i think is zero at equilibrium point. So; -ka + \frac{c}{a} = 0 (a = equilibrium point.) k = c/a2 Is it true?

Homework Statement 7. A particle of mass m moves (in the region x > 0) under a force F = −kx+c/x, where k and c are positive constants. Find the corresponding potential energy function. Determine the position of equilibrium, and the frequency of small oscillations about it...
