A particle of mass 1.5 kg moves along x-axis in a conservative force field. Its potential energy is given by V(x)=2x^(3)-9x^(2)+12x, where all quantities are written in SI units. The plot of this potential energy is given below. It is seen that the particle can be in stable equilibrium at a point on x-axis, x_(0). When it is displaced slightly from this equilibrium position, It executes SHM with time period T. What is the value of x_(0) ?
