Question

Tension in the cable supporting an elevator is equal to the weight of the elevator. From this, we can conclude that the elevator is going up or down with:
Options
A uniform velocity
Correct Answer
B variable velocity
C uniform acceleration
D variable acceleration
Correct Answer

Option A is the correct answer.

Detailed Explanation

When tension equals weight, net force is zero, so acceleration is zero. The elevator moves with constant velocity (uniform velocity).

Hint

T = mg implies a = 0.
