The Oxygen Molecule (O₂)may Be Regarded as Two Masses Connected

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 1.6 × 10−²¹ J and the effective spring constant is 86 N/m,then what is the amplitude of oscillation of each oxygen atom?

A) 3.2E-11 m
B) 1.6E-11 m
C) 1.1E-11 m
D) 6.1E-12 m
E) 4.3E-12 m
