A shell of mass m is at rest initially. It explodes into three fragments having masses in the ratio \(2:2:1\). If the fragments having equal masses fly off along mutually perpendicular directions with speed \(v,\) the speed of the third (lighter) fragment is:
1. \(3 \sqrt{2} v\) 2. \(v\)
3. \(\sqrt{2} v\) 4. \(2 \sqrt{2} v\)

A body of mass \(6~\text{kg}\) is moving from its initial position \(A\) to the next position \(B\) as shown in the figure. From \(A\) to \(B\), the value of the momentum of the body is (in SI units):

1. \(24\)
2. \(12\)
3. \(8\)
4. \(6\)
