Question

If the tension in the cable supporting an elevator is equal to the weight of the elevator, the elevator may be

Answer 1

The force in a rope or cable that pulls on an object is called the tension force. Since, tension and weight are equal in magnitude and opposite in direction, so elevator is not accelerating and the net force on it must be zero.

Going up with uniform speed.

Going down with uniform speed.

Answer 2

Explanation:

• An elevator that is hanging with the help of a rope will have a certain weight which acts as tension on the Rope by which it is hanging.
• The tension that is there on the Rope will be acting in opposite direction to the direction of the force exerted by the weight of elevator.
• Hence, when the tension and this force is equal or we can say the tension and the weight of elevator is equal then the elevator is static and is not accelerating. So, there the net force is zero.
