1. The problem statement, all variables and given/known data Let the potential energy of particle depend upon coordinate x as: U(x) = U0(1-cos(ax)). Where "U0" and "a" are constants. Find the period of small oscillations that particle performs about its equilibrium position. 2. Given Answer T = 2∏√(m/a2U0) 3. The attempt at a solution It can be seen from the equation that equilibrium will be at x = 0, where forces acting are zero. Also after integrating the equation with dx, it is seen that the motion is relevant to forced oscillations.
