Three particles are located at the corners of an equilateral triangle of side `a=sqrt(3) m`. The particles start moving with a constant speed `v=2m/ s` such that the particle initially at `A` always heads towards the particle initially at `B`. and the particle at `B` heads for the particle at `C` and the particle at `C` heads for the particle-at `A .` The magnitude of initial acceleration (in `m / s^(2)` ) of the particle at `cdot C` is
