Physics · JEE | LAWS OF MOTION

According to Hooke's law for a spring, the restoring force \( F \) for small displacements is given by \( F = -kx \), where \( k \) is the force constant. The negative sign denotes that:

1. A
   the force is in the same direction as the displacement
2. B
   the spring is rigid and inextensible
3. C
   the force is independent of displacement \( x \)
4. D
   the force is opposite to the displacement from the unstretched state
