52. The simple harmonic motion is a general phenomenon that occurs as one perturbs a system at stable equilibrium slightly away from its potential minimum. Estimate the period of the simple harmonic motion for a particle of mass m experienced a potential energy of the form U(x) = a(1/x + b²x) (Joule) as the particle is slightly pushed away from , where x is the spatial coordinate of the
