A load is suspended from a vertical spring fixed at its upper end. The load is pulled down below its equilibrium position and released, so that it undergoes vertical simple harmonic oscillations. Throughout the motion, the spring remains extended beyond its natural length.
Which row in the table correctly describes the energy of the spring-load system when the load is at its lowest point in its oscillation?
| Elastic potential energy | Gravitational potential energy | Kinetic energy | |
|---|---|---|---|
| A | Minimum | Maximum | Zero |
| B | Maximum | Minimum | Zero |
| C | Maximum | Minimum | Maximum |
| D | Minimum | Minimum | Zero |
