A body of mass M at rest explodes into three pieces, two of which of mass M/4 each are thrown off in perpendicular directions with velocities of 3 m/s and 4 m/s respectively. The third piece will be thrown off with a velocity of
Text Solution
Verified by ExpertsThe correct answer is:
C
Momentum of one piece 
Momentum of the other piece 
∴ ∴ Resultant momentum 
The third piece should also have the same momentum. Let its velocity be v, then
or
