Can anyone please help me with answering this? : A person of mass 75 kg stands on a scale inside an elevator. What can you infer about the motion of the elevator if the scale reads 735N and 900N?

Answer 1

his weight is ... 75 * g

if the scale reads his "correct" weight , the elevator is not accelerating
... if it reads less , the elevator is accelerating downward
... if it reads more , the elevator is accelerating upward
