Answer 1

Answer

The upward force by the cable is equal to the downward force of gravity.

Explanation:

If the elevator is going up at a constant speed, there is no acceleration. By the second law of newton, when there is no acceleration, there is no net force. So, the upward and downward forces should be equal. It means that the answer is

The upward force by the cable is equal to the downward force of gravity.
