Two bodies of mass 3 kg and 4 kg are suspended at the ends of massless string passing over a frictionless pulley. The acceleration of the system is \[(g=9.8\,m/{{s}^{2}})\] [MP PET 1994; CBSE PMT 2001]

• A.                         \[4.9\,m/{{s}^{2}}\]            
• B.                           \[2.45\,m/{{s}^{2}}\]            
• C.                         \[1.4\,m/{{s}^{2}}\]          
• D.                           \[9.5\,m/{{s}^{2}}\]
