Passage

Read the passage given below and answer the questions that follows: A block of mass 1 kg is placed on a rough horizontal surface. A spring is attached to the block whose other end is joined to a rigid wall, as shown in the figure. A horizontal force is applied on the block so that it remains at rest while the spring is elongated by x.

Let Fmax and Fmin be the maximum and minimum values of force F for which the block remains a equilibrium. For a particular x,

Fmax - Fmin = 2N

Also shown is the variation of Fmax + Fmin versus x, the elongation of the spring.
