Explanation:

Forces acting on the elevator:
- The tension in the cable is equal to the weight of the elevator, which is 1000 kg.
- The weight of the elevator is acting downwards with a force of 1000 kg weight.
- The tension in the cable is also acting upwards with a force of 1000 kg weight.

Analysis:
- When the tension in the cable is equal to the weight of the elevator, the net force on the elevator is zero.
- Since the net force is zero, the elevator may be at rest or in uniform motion according to Newton's first law of motion.
- If the elevator was accelerating upwards, the tension in the cable would be greater than the weight of the elevator.
- If the elevator was accelerating downwards, the tension in the cable would be less than the weight of the elevator.

Conclusion:
- Therefore, in this scenario, the elevator may be at rest or in uniform motion.
