The weight of a pilot diving down with an acceleration of 9.8ms -2 will become:
Correct answer: C. Zero
- A. Double
- B. Half
- C. Zero
- D. Negative
Explanation
When an object is in free fall, such as a pilot diving down with an acceleration equal to gravity (9.8 m/s-2), it experiences weightlessness. This occurs because the only force acting on the object is gravity, and there is no normal force counteracting it. Thus, the weight, which is the normal force exerted by a surface, is effectively zero. The other options are incorrect as they suggest changes to gravity or forces that do not apply in the context of free fall.
