Three particles A, B and C are situated at the vertices of an equilateral triangle ABC of side $l$ at an instant. Each of the particle moves with a constant speed $υ$ . A always has it’s velocity along AB, B along BC and C along CA. physical quantities for each particle in this situation at this instant is enlisted in list I. Corresponding values (in SI units) is enlisted in list-II. (Take $l = 2 m$ ; $υ = \sqrt{3} m / s$ )
List I
List II
I) Angular velocity of velocity vector (i.e. rate of rotation of velocity vector) P) 1.3
II) Linear acceleration Q) 0.97
III) Angular acceleration of velocity vector R) 2.3
IV) Radius of curvature of path S) 0.75
