How does the normal reaction compare to the person’s weight?, Equal to weight, Greater than weight, Less than weight, Zero, A lift is accelerating downwards at a rate less than g., Greater than weight, Equal to weight, Less than weight, Zero, A lift is moving with constant velocity. What is the normal reaction on a person inside?, 0, mg, 2 mg, Less than mg, Taking upwards as positive, the normal reaction in a lift is given by R=m(g+a).
