A rod 
of length 
is placed at the edge of a smooth table as shown. It is hit horizontally at point 
. If the displacement of centre of mass in 
is 
, then the angular velocity of the rod is (Take, 
)
A
30 rads 
B
20 rads 
C
D
5 rads 
Text Solution
Verified by ExpertsThe correct answer is:
A
Given, length of 
Net Displacement of centre of rod 
Displacement in 
direction
Since, angular impulse 
change in angular momentum 
[As horizental impulse]
