Two sphere `A and B` of masses `m_(1) and m_(2)` respectivelly colides. A is at rest initally and `B` is moving with velocity `v` along x-axis. After collision `B` has a velocity `(v)/(2)` in a direction perpendicular to the original direction. The mass `A` moves after collision in the direction.

Options

A. `theta=tan^(-1)((1)/(2))" to the x- axis"`
B. `theta=tan^(-1)(-(1)/(2))" to the y - axis"`
C. Same as that of B
D. Opposite to that of B

Answer

A
