Question 2

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
