An elevator’s motion is through the action of a single cable. The elevator has a gravitational force of 2000 N. When the elevator is moving downwards at a constant velocity, how much tension is in this cable?
  • a)
    slightly less than 2000 N
  • b)
    equal to 2000 N
  • c)
    greater than 2000 N
  • d)
    close to 0 N
Correct answer is option 'B'. Can you explain this answer?

  • Drawing a free-body diagram of a elevator in motion will elucidate the forces on the elevator.
  • The forces on the elevator when it is moving downwards at a constant velocity are the gravitational force and the force due to the tension on the cable.
  • If the elevator is moving at constant velocity, then there is no net acceleration and no net force. The tension in the cable must equal the gravitational force of the elevator.

Explanation:

Gravitational force in the elevator:
- The gravitational force acting on the elevator is 2000 N, which is the weight of the elevator.

Tension in the cable when moving downwards:
- When the elevator is moving downwards at a constant velocity, the tension in the cable is equal to the gravitational force acting on the elevator.
- This is because the tension in the cable must exactly balance the gravitational force to keep the elevator moving at a constant velocity.

Answer:
- Therefore, the tension in the cable when the elevator is moving downwards at a constant velocity is equal to 2000 N.

Conclusion:
- The correct answer is option B, which states that the tension in the cable is equal to 2000 N when the elevator is moving downwards.
