If the speed of rotation of the Earth is increased, the mass lying on its surface will be:
Correct answer: D. Have no change in weight
- A. Increased in weight
- B. Decreased in weight
- C. Some time increase & some time decrease
- D. Have no change in weight
Explanation
D is the correct option. The weight of an object is determined by the gravitational force acting on it, which depends on the mass of the object and the mass of the Earth. The Earth's rotation speed, within reasonable limits, does not significantly impact the weight of objects on its surface.
