In the figure, the blocks A, B and C of mass m   each have acceleration \(a_{1}\), \(a_{2}\) and \(a_{3}\) respectively.\(F_{1}\) and \(F_{2}\) are external forces of magnitudes 2 mg and mg respectively then:
  1. \(a_{1}=a_{2}=a_{3}\)
  2. \(a_{1}>a_{3}>a_{2}\)
  3. \(a_{1}=a_{2}, a_{2}>a_{3}\)
  4. \(a_{1}>a_{2}, a_{2}=a_{3}\)

Answer

(B) a_ 1 >a_ 3 >a_ 2
