A) \[o.64\times {{10}^{-10}}m\]
B) \[o.56\times {{10}^{-10}}m\]
C) \[o.51\times {{10}^{-10}}m\]
D) \[o.48\times {{10}^{-10}}m\]
Correct Answer: A
Solution :
Key Idea: The cartesian co-ordinate of the centre of mass is \[\frac{\underset{i}{\mathop{\Sigma }}\,{{m}_{i}}{{x}_{i}}}{\Sigma {{m}_{i}}}\] Let the distance of the centre of mass from the carbon atom be r. The mass of carbon, \[{{m}_{1}}=12\text{ }amu\] The mass of oxygen, \[{{m}_{2}}=16amu\]You need to login to perform this action.
