The mass of two objects {\A} and {\B} are 100 {\g} and 300 {\g} respectively. Their velocities are \overrightarrow{v_{ {\A}}=(\hat{i}+7 \hat{j}) {\m} \/ { s} and \overrightarrow{v_B}=(\hat{j}-6 \hat{i}) {\m} \/ { s}. What will be the velocity of centre of mass in {\m} \/ { s} ?

Correct Answer is : −174∧i+52∧j

-\frac{4}{17} \hat{i}+\frac{5}{2} \hat{j}

-\frac{17}{4} \hat{i}+\frac{5}{2} \hat{j}

-\frac{17}{4} \hat{i}+\frac{2}{5} \hat{j}

-\frac{4}{17} \hat{i}+\frac{2}{5} \hat{j}
