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. same as that of B
B. opposite to that of B
C. `theta = tan^(-1) (1/2)` to the x-axis
D. `theta = tan^(-1) (-1/2)` to the x-axis
