The time period of a particle ‘P' moving along a circular path of radius 1 cm is π s. Another particle ‘Q' starts from rest at a point A and travelling along a straight line path reaches the point B in 2 s. If AB =12 cm and the particles P and Q are respectivelyat D and B at an instant shown in the figure, the acceleration of particle Q with respect to particle P is __________ cms−2 . (Points A. B. C. D and O lie along the same straight line)
