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

question 27

Multiple Choice

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
