1.	A student says that he had applied a force F= - r/x on a particle and the particle moved in simple harmonic motion. He refuses to tell whether r is a constant or not. Assume that he was worked only with positive x and no other force acted on the particle
Answer» As X increases K increases As x increases K decreases As x increases K remains constant The MOTION cannot be simple harmonic ANSWER :A
