Two spheres A and B of masses \[{{m}_{1}}\] and \[{{m}_{2}}\] respectively collide. A is at rest initially and B is moving with-velocity v along x-axis. |
After collision B has a velocity \[\frac{v}{2}\] in a direction perpendicular to the original direction. The mass A moves after collision in the direction [AIPMT (S) 2012] |
A) same as that of B
B) opposite to that of B
C) \[\theta ={{\tan }^{-1}}\left( \frac{1}{2} \right)\] to the x-axis
D)
\[\theta ={{\tan }^{-1}}\left( \frac{-1}{2} \right)\]
Correct Answer: C
