A mass 'M' moving with velocity 'V' along X-axis collides and sticks to another mass 2M which is moving along Y-axis with velocity '3 V'. The velocity of the combination after collision is
1
\(\frac{V}{3} \hat{i}+2 V \hat{j}\)
2
\(\frac{V}{2} \hat{i}+V \hat{j}\)
3
\(\frac{V}{3} \hat{i}-2 V \hat{j}\)
4
\(\frac{V}{2} \hat{i}-V \hat{j}\)
