A block ' \( A \) ' of mass ' \( m \) ' is attached at one end of a light spring and the other end of spring is connected
\( \mathrm{P} \) to another block ' \( B \) ' of mass \( 2 \mathrm{~m} \) through a light string as shown in the figure. ' \( A \) ' is held and \( B \) is in static
W. equilibrium. Now \( A \) is released. The acceleration of \( \mathrm{A} \) just after that instant is ' \( a \) '. In the next case, \( B \) is held and \( A \) is in static equilibrium. Now when \( B \) is released, its acceleration immediately after the release is ' \( b \) '. The value of \( a / b \) is: (Pully, string and the spring \( A m \quad 2 m B \) are massless)
