A body of mass (4m) 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 ( υ ). The total kinetic energy generated due to explosion is :
A
m υ 2
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
B
p i = p f
O = mv 
+ mv 
+ 2m 
=
