Given below are two statements:
| Assertion (A): | The gravitational potential energy associated with a particle-earth system depends on the vertical position (or height) of the particle relative to the reference position, not on the horizontal position. |
| Reason (R): | For any height h above earth's surface, the potential energy of the particle is mgh |
