Two bodies of mass 1 kg and 3 kg have the position vectors \(\hat{i}+2 \hat{j}+\hat{k} \text { and }-3 \hat{i}-2 \hat{j}+\hat{k}\) respectively. The centre of mass of this system has the position vector
- \(-2 \hat{i}+2 \hat{k}\)
- \(-2 \hat{i}-\hat{j}+\hat{k}\)
- \(2 \hat{i}-\hat{j}-2 \hat{k}\)
- \(-\hat{i}+\hat{j}+\hat{k}\)
Answer
(B) -2 i - j + k
