← ScienceWhich risk occurs when an elevator’s cable breaks because of complete failure under tension?
A)Uncontrolled downward acceleration into freefall ✓
B)Upward force due to cable momentum
C)Sudden thermal expansion causing binding
D)Electromagnetic interference disrupting controls
💡 Explanation
Uncontrolled downward acceleration arises instead, because in freefall, the equivalence principle implies that the sensation gravity disappears within the elevator, therefore the occupants experience weightlessness rather than crushing.
