Question

Four masses of \(1\text{ kg}, 2\text{ kg}, 3\text{ kg}\) and \(4\text{ kg}\) are kept at co-ordinates \((0, 0)\text{m, (0, 1)\text{m}\) and \((1, 0)\text{m}\) respectively. Using the co-ordinates of centre of mass its position vector is}

• A. \(0.5\hat{i} + 0.7\hat{j}\)
• B. \(0.7\hat{i} + 0.5\hat{j}\)
• C. \(0.4\hat{i} + 0.6\hat{j}\)
• D. \(\hat{i} + \hat{j}\)
