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

The time period of a particle in simple harmonic motion is equal to the time between consecutive appearances of the particle at a particular point in its motion. This point is:

1. | the mean position |

2. | an extreme position |

3. | between the mean position and the positive extreme |

4. | between the mean position and the negative extreme |
