In the figure shown, the coefficient of static friction between B and the wall is 2/3 and the coefficient of kinetic friction between B and the wall is 1/3. Other contacts are smooth. The minimum force ‘F’ required to lift B, up is F₀. Now if the force applied on A is slightly increased than F₀, then find the acceleration of B. Mass of A is 2m and the mass of B is m. Take tan$\theta$ = 0.75 (g = 9.8 m/s²)
