Asked by Sandhya
An object of mass m is hanging by a string from the roof of an
elevator. We want to compare the tension in the string due
to the weight of the object under various conditions. Which
statements are true?
Choices: True, False.
A. If the elevator is moving upwards, and speeding up, the
tension in the string is equal to the object's weight
B. If the elevator is moving up at constant speed, the tension in the string is equal to the object's weight
C. If the elevator is moving downwards, and speeding up,
the tension in the string is less than the object's weight
D. If the elevator is moving downwards in free fall, the
tension in the string is equal to the object's weight
E. If the elevator is moving upwards, but slowing down,
the tension in the string is equal to the object's weight
