When displaced from equilibrium by a small amount, the two hydrogen atoms in an H2 molecule are acted on by a restoring force Fx = k1x with k1 = 530 N/m. Calculate the oscillation frequency f of the H2 molecule. Use meff = m/2 as the "effective mass" of the system, where m in the mass of a hydrogen atom. Take the mass of a hydrogen atom as 1.008 u, where 1 u = 1.6611027 kg. Express your answer in hertz.
