A shell of mass 15 kg, initially a rest, explodes into three fragments of masses in the ratio 1:1: 3. The fragments with equal masses fly off in mutually perpendicular directions with a speed of 6 ms^(-1) The speed of the heaviest fragment will be :

A bomb of mass 6kg initially at rest explodes in to three identical fragments On of the fragments moves with a velocity of 10sqrt3 hatim//s another frament moves with a velocity of 10 hatj m//s then the thired fragment moves with velocity of magnitude .
