A spherical ball A of mass 4 kg, moving along a straight line strikes another spherical ball B of mass 1 kg at rest. After the collision, A and B move with velocities 
respectively making angles of 
and 
with respect to the original direction of motion of A. The ratio 
will be:
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
A
:
Applying the law of conservation of linear momentum along a direction perpendicular to the direction of motion (i.e. along y - axis), we get
