An object weighs 9 N on the surface of the Earth. What would be its weight, when measured on the surface of a planet where the acceleration due to gravity is 9 times that on the surface of the Earth?
- A. The weight would remain the same
- B. The weight would be equal to 1 N
- C. The weight would become 9 times ✓
- D. The weight will be reduced to \frac{1}{9} N
Correct Answer: C. The weight would become 9 times
Explanation
Weight is the product of mass and acceleration due to gravity (W = mg). If the acceleration due to gravity is 9 times that on Earth, the new weight will be 9 \times 9 = 81 N, which is 9 times the original weight.
