A block of mass `m` is attached with a massless spring of force constant `k`. The block is placed over a fixed rought inclined surface for which the coefficient of friction is `mu=(3)/(4)` . The block of mass `m` is initially at rest . The block is mass `M` is released from rest with spring in unstretched state. The minimum value of `M` required to move the block up the plane is `(` neglect mass of string and pulley and friction in pulley `)`
