Read the following short write-up and answer the questions at the end of it.
Figure shows a system of 2 blocks of mass \( m \) and 6 small blocks of mass \( m / 2 \) each. All surfaces are frictionless and the string and the pulley are ideal. Assume negligible space between the blocks.
40. Find the acceleration of block \( C \) just after block \( A \) leaves the horizontal surface and starts moving down.
(A) \( g / 5 \)
(B) \( 2 g / 9 \)
(C) \( g \)
(D) none of these
41. Find the acceleration of block \( A \) in the above question.
(A) \( g / 5 \)
(B) \( 2 g / 9 \)
(C) \( g \)
(D) none of these
42. Magnitude of relative acceleration of block \( A \) and block \( C \) will be
(A) \( 1 / 45 g \)
(B) \( 4 / 5 g \)
(C) \( 7 / 9 g \)
(D) none of these
