A body of mass 
is lying in x‐y plane at rest. It suddenly explodes into three pieces. Two pieces, each of mass (m) move perpendicular to each other with equal speeds (v). The total kinetic energy generated due to explosion is
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
B
:
Let 
be velocity of third piece of mass 
Initial momentum, 
(As the body is at rest) Final momentum, 
According to law of conservation of momentum
The magnitude of 
is
Total kinetic energy generated due to explosion 1 2 1 2 1
