Two spheres A and B of masses 
and 
respectively collide. A is at rest initially and B is moving with velocity v along x‐axis. After collision B has a velocity in a direction perpendicular to the original direction. The mass A moves after collision in the direction
A
same as that of B
B
opposite to that of B
C
to the 
‐axis
D
to the 
‐axis (2012)
Text Solution
Verified by ExpertsThe correct answer is:
D
:
According to law of conservation of linear momentum along x ‐ axis, we get
or 
(i)
According to law of conservation of linear momentum along y ‐ axis, we get
, (ii) Divide (ii) by (i), we get
or 
to the x ‐ axis
