Dear paidepelly


Let the maximum compression given to spring is x


Force acting on a block is

Normal reaction (N) in the verticle direction from the surface

mg force in the downward direction.

spring force =kx

frictional force =YN in the apposite direction of spring force


now block will not move if YN≥kx

or x ≤YN/k

    x≤Ymg/k
