Question

An elevator is pulled upward at a constant speed by a cable. Which statement is true about the forces acting on the elevator? A. There is a net downward force on the elevator due to gravity. B. The upward force by the cable is smaller than the downward force of gravity. C. The upward force by the cable equals the downward force of gravity. D. There are no forces acting on the elevator because it is traveling at constant speed. E. The upward force by the cable is greater than the downward force of gravity.

Explanation / Answer

C. The upward force by the cable equals the downward force of gravity.

since the elevator is moving at constant speed, the acceleration is zero and so is the net force. hence the upward force equals downward force
