The minimum value of m will be when 3 kg block slides downward. The forces acting on blocks as shown
At equilibrium
T=mgsin⁡θ+μmgcos⁡θ..........(i)
As pulley is frictionless so, the tension T will be same in whole string,
So,T+3×μgcos⁡θ=3×gsin⁡θ.............(ii)
Putting the values of μ and θ in (i) and (ii) and solved
