A rod of mass M and length L is lying on a horizontal frictionless surface. A particle of mass 'm' travelling along the surface hits at one end of the rod with a velocity 'u' in a direction perpendicular to the rod. The collision is completely elastic. After collision, particle comes to rest. The ratio of masses 
is 
. The value of 'x' will be ___
Text Solution
Verified by ExpertsThe correct answer is:
CHECK THE SOLUTION.
(4)
Just before collision
Just after collision
From momentum conservation, 
mu=Mv …. (i)
From angular momentum conservation about O,
…. (i)
From 
X=4
