Q: A shell of mass 5 M, acted upon by no external force and initially at rest , bursts into three fragments of masses M , 2M and 2M respectively. The first two fragments moves in opposite directions with velocities of magnitudes 2V and V respectively the third fragment will

(a) Move with a velocity V in a direction perpendicular to the other two

(b) Move with a velocity 2V in the direction of velocity of the first fragment

(c) Be at rest

(d) Move with a velocity V in the direction of velocity of the second fragment

Ans: (c)
