As per the given figure, a small ball 
slides down the quadrant of a circle and hits the other ball 
of equal mass which is initially at rest. Neglecting the effect of friction and assume the collision to be elastic, the velocity of ball 
after collision will be:
A
0
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
C
Energy conservation for ' 
'
Now collision between 
and 
is elastic and both have same mass then 
will transfer all velocity to then 
. So velocity 
will be
