three particles P,Q,R of equal masses are placed at the corner of an equilqteral triangle ABC . now a particle P starts with a speed V along AB ,particle Q statrs with speed 2V along BC andRstarts with a speed V along CA siumentaneusly.the displacement of centre of mass in time t is A vt/3 parallel BC b 2vt/3 parallel to BC C ROOT3 VT/2 parallel AC d root3vt parallel to AC
