Problem
A lamp hangs motionless from the ceiling by two identical vertical cords. One of the cords suddenly snaps while the other remains attached. Which statement best describes the lamp’s motion immediately after the cord breaks?
(a) It accelerates downward at g because the remaining cord can no longer exert any upward force.
(b) It remains at rest because the tension in the single remaining cord instantly doubles to balance the lamp’s weight.
(c) It accelerates downward because the remaining upward force is smaller than its weight.
(d) It accelerates downward at g/4 because removing one cord halves the supporting force.
