Question

Three blocks are connected on a horizontal frictionless table by two light strings, one between m1 and m2, another between m2 and m3 . The tensions are T1 between m1 and m2 and T2 between m2 and m3. if m1 = 1 kg, m2 = 8 kg, m3 = 27 kg and F = 36 N applied on m3, then T2 will be

  1. 18 N    
  2. 9 N    
  3. 3.375 N    
  4. 1.75 N    

The correct answer is: 9 N
