An object has ________ weight in outer space and during free fall.
✓
Answer
An object has zero weight in outer space and during free fall. Explanation: An object kept in a lift which falls freely, weighs zero on the weighing machine, but its actual weight is still mg. This happens because the normal reaction force exerted on the object in the lift is equal to zero, and normal force equals to mg, which in turn equals the weight of the object.
