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.

Correct Answer is : θ=tan−1(−1/2) to the x-axis

\theta=\tan ^{-1}(1 / 2) to the x-axis

\theta=\tan ^{-1}(-1 {/} 2) to the x-axis
