Problem

A block on a frictionless horizontal surface is attached to a spring. The positive xx-direction is defined to the right. The block is pulled 0.10 m0.10\,\text{m} to the right and held at rest. Which statement best describes the direction of the spring force acting on the block while it is held in this displaced position? (a) To the right, in the same direction as the displacement\text{To the right, in the same direction as the displacement} (b) There is no spring force because the block is at rest\text{There is no spring force because the block is at rest} (c) To the left, opposite the displacement\text{To the left, opposite the displacement} (d) Vertically downward, dominated by gravity\text{Vertically downward, dominated by gravity}
