Three particles A, B and C of equal masses move with equal speeds v along the medians of an equalateral triangle. They collide at the centroid O of the triangle. After collision A comes to rest while B retraces its path with speed v. The velocity of C is then
- v, direction\(\overrightarrow{\mathrm{OA}}\)
- 2v, direction\(\overrightarrow{\mathrm{OA}}\)
- 2v, direction\(\overrightarrow{\mathrm{OB}}\)
- v, direction\(\overrightarrow{\mathrm{BO}}\)
Answer
(D) v, direction BO
