Three particles of masses 1 kg, 2 kg and 3 kg are situated at the comers of an equilateral triangle move at speed \[6\,m{{s}^{-1}}\], \[3\,m{{s}^{-1}}\] and \[2\,m{{s}^{-1}}\] respectively. Each particle maintains a direction towards the particle at the next comer symmetrically. Find velocity of CM of the system at this 2kg 4 instant

• A. \[3\,m{{s}^{-1}}\]                  
• B. \[5\,m{{s}^{-1}}\]
• C. \[6\,m{{s}^{-1}}\]      
• D. Zero
