molecule is \( 1,13 \AA \). Locate the centre of mass of the molecule relative to carbon atom.
[0.602 A ]
2. Two bodies of masses 2 g and 10 g have position vectors \( 3 \hat{i}+2 \hat{j}-\hat{k} \) and \( \hat{i}-\hat{j}+3 \hat{k} \) respectively. Find the position vector and distance of C.M. from the ongin.
\[
\left[\frac{1}{6}(18 \hat{i}-3 \hat{j}+14 \hat{k}) ; 2.73 \text { units }\right]
