A student says that he had applied a force \(=-k\sqrt x\) on a particle and the particle moved in simple harmonic motion. He refuses to tell whether k is a constant or not. Assume that he has worked only with positive x and no other force acted on the particle.
1. As x increases k increases
2. As x increases k decreases
3. As x increases k remains constant
4. The motion cannot be simple harmonic
