Question

What will happen to a body in a lift moving downward with acceleration greater than g?

• A. Body will remain on the floor
• B. Body will rise up toward the ceiling
• C. Body will weigh more than its actual body weight
• D. Body will start rotating

Answer 1

The correct option is B Body will rise up toward the ceiling

Normal reaction N of body inside a lift accelerating downward.
N = m(g – a)
If a > g
Then N < 0.
This means there will be a net upward force on the body due to this the body will rise upward.
