Question

6. A person who weighs 600 N is standing on a scale in an elevator. The elevator is
identical in both cases. In both cases the elevator is moving downward, but in Case A it
is accelerating upward and in Case B it is accelerating downward. Will the scale reading
be (a) greater in case A, (b) greater in case B, or (c) the same in both cases? Explain.
​

Answer 1

Answer:

Option A, greater in case A

Explanation:

Case A

N-W=ma

N=W+ma

Where a is acceleration, m is mass, W is weight

Case B

W-n=ma

N=W-ma

Therefore, the reading is greater in case A
