A uniform rod of length 
and mass 
is pivoted at its centre 
. Two masses 
and 
with speed 
, 
as shown strikes the rod and stick to the rod. Initially the rod is at rest. Due to impact, If it rotates
with angular velocity 
then 
will be
A
B
Zero
C
D
Text Solution
Verified by ExpertsThe correct answer is:
A
: Final linear momentum, 
.
Zero linear momentum means the rod can have only angular momentum after the masses strike it.
Now, total angular momentum 
.
From the conservation of angular momentum,
angular momentum 
or
