A particle of mass M moves in one dimension along the positive x axis, under the influence of two forces. The first force is a constant force, with magnitude B and direction toward the origin. The second force is an inverse square law, with magnitude A/x2 and direction away from the origin. Calculate the frequency of small oscillations around the equilibrium. [Data: M = 0.37 kg; B = 18 N; A = 47 Nm2.]
