Two blocks A and B of equal mass m are connected through a massless string and arranged as shown in figure. Friction is absent everywhere. When the system is released from rest

  1. tension in string is mg over 2
  2. tension in string is mg over 4
  3. acceleration of A is fraction numerator text  g  end text over denominator 2 end fraction
  4. acceleration of A is 3 over 4 g

The correct answer is: acceleration of A is 3 over 4 g
