Block A of mass m and block B of mass 2m are placed on a fixed triangular wedge by means of a massless, inextensible string and a frictionless pulley as shown in figure. The wedge is inclined at 45^∘ to the horizontal on both the sides. If the coefficient of friction between the block A and the wedge is (2)/(3) and that between the block B and the wedge is (1)/(3) and both the blocks A and B are released from rest, the acceleration of A will be:
