The oxygen molecule (O2) may be regarded as two masses connected by a spring. In vibrational motion, each oxygen atom alternately approaches, then moves away from the center of mass of the system. If each oxygen atom of mass m = 2.67 × 10^-26 kg has a vibrational energy of 6.4 × 10^-21 J and the effective spring constant is 50 N/m, then what is the amplitude of oscillation of each oxygen atom?
a. 3.2 × 10^-11 m
c. 1.1 × 10^-11 m
b. 1.6 × 10^-11 m
d. 8.0 × 10^-12 m
