A particle undergoes an elastic collision with an identical particle at rest. After the collision, the two particles move with velocities \(\vec{v_1},~\vec{v_2}.\) Final velocities \(\vec{v_1},~\vec{v_2}\) are in different directions. The angle between \(\vec{v_1}\) and \(\vec{v_2}\) is:
1. \(\dfrac{\pi}{6}\)
2. \(\dfrac{\pi}{3}\)
3. \(\dfrac{\pi}{2}\)
4. \(\dfrac{2\pi}{3}\)
1. \(\dfrac{\pi}{6}\)
2. \(\dfrac{\pi}{3}\)
3. \(\dfrac{\pi}{2}\)
4. \(\dfrac{2\pi}{3}\)
