Physics - NLM Question with Solution | TestHub

Block A of mass $\mathrm{m}$ and block $\mathrm{B}$ of mass $2\mathrm{m}$ 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 $45^{\circ }$ to the horizontal on both the sides. If the coefficient of friction between the block $\mathrm{A}$ and the wedge is $2/3$ and that between the block $\mathrm{B}$ and the wedge is $1/3$ and both the blocks $\mathrm{A}$ and $\mathrm{B}$ are released from rest, the acceleration of A will be
